0d90cda0be bdev/rbd: Save comp varaible in bdev_io structure
Purpose: Better to put this varable into the bdev_rbd_io structure
instead of on the stack. And we will use this variable in next patch,
when the callback function is completed, so we should not put it on the stack.

75f1d6484a bdev/nvme: Aggregate multiple ctrlrs into a single bdev ctrlr
This patch enables us to aggrete multiple ctrlrs in the same NVM
subsystem into a single bdev ctrlr to create multipath.

This patch has a critical limitation that ctrlrs which are aggregated
need to have no namespace. Hence any nvme bdev is not created.
However it will be removed in the next patch.

The design is as follows.

A nvme_bdev_ctrlr is created to aggregate multiple nvme_ctrlrs in
the same NVM subsystem. The name of the nvme_ctrlr is changed to be
the name of the nvme_bdev_ctrlr.

NVMe bdev module has both the failover feature and the multipath
feature now. To choose which of failover or multipath to use, add an new
parameter multipath to the RPC bdev_nvme_attach_controller.

When we attach a new trid to the existing nvme_bdev_ctrlr, we use the failover
feature if multipath is false, we use the multipath feature if multipath is
false.

nvme_bdev_ctrlr has a list for nvme_ctrlr and it is guarded by the
global mutex. Callers can query nvme_ctrlrs from a nvme_bdev_ctrlr via
trid as a key. nvme_bdev_ctrlr is not registered as io_device.

14535253f1 bdev/nvme: Reset the nvme_ctrlr if an I/O qpair is disconnected
Previously, if an I/O qpair is disconnected, we tried reconnecting
the qpair. However, this reconnect operation was very likely to fail
and will not match the upcoming asynchronous connect/reconnect
operation. We need an extra callback to make this reconnect operation
asynchronous, but we do not want to have it.

Hence if an I/O qpair is disconnected, we free the I/O qpair and then
reset the corresponding nvme_ctrlr immediately. If the admin qpair is
also disconnected, the nvme_ctrlr is reset immediately. However this
event may never happen. So we do not wait for the error of the admin
qpair.

The NVMf host may disconnect connections by itself intentionally.
In this case, resetting the nvme_ctrlr will surely fail. But resetting
the nvme_ctrlr frees all I/O qpairs of the nvme_ctrlr and these I/O
qpairs are not created again until resetting the nvme_ctrlr succeeds.
Resetting the nvme_ctrlr once at most is more efficient than repeating
reconnecting the I/O qpair. So this change is valuable even for such
intentional disconnection. However, it is helpful to know the event that
I/O qpair is disconnected. Hence change DEBUGLOG to NOTICELOG in the
disconnected callback. The disconnected callback is not repeated, and
we do not need to worry about NOTICELOG flooding.

Refine the unit test case to verify this change.

87e9ae4035 bdev/nvme: Poll group manages ctrlr channels for qpair disconnect
Poll group has a list of the associated ctrlr channels to update
them when the corresponding I/O qpair is disconnected to do path
failover.

Another idea is that poll group has a list of the associated bdev
channels. However, two or more bdev channels may share a single
ctrlr channel and I/O qpair is per ctrlr channel. What we want to do
by this addition is to stop I/O submission to any failed I/O qpair
and choose alternative I/O qpair. Hence we take the first idea.

2ee6ab36f9 bdev/nvme: bdev_nvme_reset() follow spdk_nvme_ctrlr_reset() about return value
Previously bdev_nvme_reset() returned -EBUSY if ctrlr is being
destructed and returned -EAGAIN if ctrlr is being reset.

These did not match what spdk_nvme_ctrlr_reset() returned.

Reset operation will be more important than current when multipath
is supported and reset operation is made asynchronous.

Hence change bdev_nvme_reset() to follow spdk_nvme_ctrlr_reset().
bdev_nvme_reset() returns -ENXIO if ctrlr is being destructed and
returns -EBUSY if ctrlr is being reset.

Additionally change the return value of bdev_nvme_failover()
accordingly. After the change bdev_nvme_failover() returns -ENXIO
if being destructed and returns -EBUSY if ctrlr is being reset.

b0a6496a7b bdev/nvme: Save probe_ctx in nvme_ns and populate_namespace_done() refer it
nvme_ctrlr_populate_namespace_done() needs nvme_ns, probe_ctx, and completion
status.

When multipath is supported, nvme_ctrlr_populate_namespace_done() will
be called from the spdk_for_each_channel() callback. The spdk_for_each_channel()
callback can have one context and one completion status.

Hence nvme_ns or probe_ctx need to have another.

If an nvme_ctrlr has multiple namespaces, a probe_ctx is shared by
multiple nvme_ns.

So let nvme_ns has probe_ctx.

fbbc8c4f81 bdev/nvme: Restore the removed async callbacks for populating namespaces
For multipath, when an new nvme_ns is added to an existing nvme_bdev,
we need to add the corresponding qpair to all existing nvme_bdev_channels
dynamically. The RPC bdev_nvme_attach_controller has to return after that.
Hence populating namespace needs to be asynchronous.

On the other hand, when an nvme_ns is removed from an existing nvme_bdev,
we need to remove the corresponding qpair from all existing nvme_bdev_channels
dynamically. Hence depopulating namespace needs to be asynchronous.

By the recent refactoring, two callbacks, nvme_ctrlr_populate_namespace_done()
and nvme_ctrlr_depopulate_namespace_done() were removed accidentally.
We need to restore these.

282b8b70a7 bdev/nvme: Don't allocate inactive namespaces
If the number of namespaces is very large, this can cause excessive
memory allocation. This is especially true because when the number of

for handling the schedulers.
Three schedulers and a governor were moved to scheduler modules
from event framework.

This will allow next patch to add JSON RPC configuration
to the whole subsystem.
Along with easier addition of other schedulers.

a03bc55669 uring: Fix socket rotation and ordering issue in the pending_recv list.
When we rotate the socket in the list, we did not check whether the uc pointer
is NULL, then we cause the coredump when using uc pointer.

When we add a new socket (with pollin event) into the pending_recv list,
we add it into the end of the pending_recv list, then it delays the execution
of the newly socket, and it can cause the timeout especially when a socket
is in a connection phase.

So the purpose of this patch is:
1 Revise the rotation logic to handle the two cases, i.e., (1)sock is in the
beginning of the list; (2)sock is in the end of list. The purpose is
to avoid NULL pointer access, and efficently handle the exceptional case.

2 When there is new pollin event of the socket, we should add socket in the beginning
of the list. And this can avoid the new socket handling starvation.
Since max poll event num is 32 from upper layer and if we always put the new socket
in the end of the list, then starvation will occur if there are many socket connection events.
Because if we add the new socket into the end of the pending list, we will always handle the
existing socks first, then the later coming socket(with relatively pollin event) will always be
handled late. Then in the sock connection initialization phase, it will consume a relatively
long time, then the upper layer connection based on this socket will cause timeout,.e.g.,

ctrlr.c: 185:nvmf_ctrlr_keep_alive_poll: *NOTICE*: Disconnecting host nqn.2014-08.org.nvmexpress:

efbab14933 bdev/nvme: Separate attach_cb between creating ctrlr and setting failover
The NVMe bdev module will have two similar features, multipath and
failover when it supports multipath.

Take a case that we add two different trids with the same name by the
bdev_nvme_attach_controller RPC as an example.

The failover adds secondary trid to an existing nvme_ctrlr. The multipath
feature creates another nvme_ctrlr and adds it to the same nvme_bdev_ctrlr
which has an existing nvme_ctrlr.

We want to use bdev_nvme_attach_controller for both failover and multipath.
To do it cleanly, separate callback to spdk_nvme_connect_async() between
creating ctrlr and setting failover.

abb4baef2d bdev/rbd: make destruct path asynchronous
When a bdev is being unregistered, after all
channels have been closed, the bdev layer calls
the module's destruct callback for the bdev before
calling the bdev unregister callback.

For the rbd module, the destruct callback is
bdev_rbd_destruct.  This callback unregisters the
rbd io_device which is an asynchronous operation.
We need to return >0 from bdev_rbd_destruct to
inform the bdev layer that this is an asynchronous
operation, so that it does not immediately call
the bdev unregister callback.  Once the rbd io_device
is unregistered, we can call spdk_bdev_destruct_done()
which will trigger the bdev layer to finally call
the bdev unregister callback.

Without this fix, deleting an rbd bdev would
complete before the backing cluster reference
had been released.  This meant that even
if you had deleted all rbd bdevs, there might still
be cluster references in place for a short period of
time.  It's better to wait to complete the delete
operation until the cluster reference has been
released to avoid this issue (which this patch
now does).

Fixes issue #2069.

a70aae4610 bdev_rbd: do final clean up on main_td
The bdev layer doesn't call the destruct callback until
all channels have been released, but because the channel
delete callback passes message to the main thread, we can
end up with a complicated race condition.  Currently we
have a deferred_free code path to handle this race, but
we can handle this a bit more cleanly by doing the
construct operation on the main_td as well.

This also simplifies the next patch which will
asynchronously destruct the bdev to fix an RPC bug.

Here's the race:

1) first channel was created on thread A, so disk->main_td = thread A
2) second channel was created on thread B
3) first channel is freed (but disk->main_td is still thread A)
4) spdk_bdev_unregister is called on thread C
5) bdev layer gives callback on thread B to upper layer
6) upper layer on thread B frees channel
7) bdev_rbd_destroy_cb runs on thread B and has to send msg to thread A
   for processing
8) bdev layer calls bdev_rbd_destruct on thread C (since step #4 was on
   thread C)

This patch makes use of async_fini_start flag to
make fini_start asynchronous.

During this time all lvol stores which have no open
lvols are unloaded. This is required, since lvs
holds claim on the underlying bdev.

Fixes #1630

Callback for bdev modules is called 'module_fini',
meanwhile after its execution bdev modules were to call
'spdk_bdev_module_finish_done()'.

This function carries incorrect name, so it was deprecated
and replaced with 'spdk_bdev_module_fini_done()'.

413d25b036 bdev_module: add async fini_start()
fini_start() is called for each bdev module before
iterating over all unclaimed bdevs to unregister them.
This allows bdev modules to behave differently during
each such unregister. Ex. unloading lvol store when
all lvol bdevs on it are unregistered.

Another use of this callback is to unclaim all bdevs
that can be at that point. Especially ones that will
not receive callback due to no bdev registered.
Ex. offline raid bdev, when some underlying bdevs are missing.

fini_start() being synchronous does not help in cases
where to release claim on the bdev, an asynchronous operation
is required. Ex. lvol store with no bdevs present, requires
async lvs unload to be called.

This patch adds async_fini_start flag for the bdev modules,
to be used when async fini_start is required. When done,
bdev module has to call spdk_bdev_module_finish_start_done().

d2dd47433b bdev/lvol: remove lvs with lvols during application shutdown
Once bdev finish starts, bdev unregister is called on all
unclaimed bdevs. This means that for lvs with at least one
lvol present, there will be a corresponding bdev unregister.

Yet the vbdev_lvol module does not attempt to unload the lvs,
once last lvol from that lvs is unregistered. Leaving
the base bdev for lvs claimed.

This patch fixes that by using fini_start callback from
bdev_module to mark when shutdown begins. After that
last lvol unregistered on lvs will unload it.

Expanded struct lvol_bdev to contain lvol_store_bdev.
Closing the lvol will free spdk_lvol, so lvol->lvol_store cannot
be accessed.

Changed ut_lvol_destroy UT to ut_bdev_finish. Previous UT didn't
really test vbdev_lvol_destroy, but 'hotremove' of the lvol bdev.
In effect there is no hotremove of the lvol bdevs (only lvs bdev).
spdk_bdev_unregister() can only be called from within vbdev_lvol,
or during bdev module finish.
This UT will now check the bdev module finish.

Note that at this point lvs with no lvols will not trigger
lvs unload. Next patches in series will introduce async fini_start,
to allow for the unload.

074a63d507 bdev/ocf: Fix devices block size mismatch
OCF creates vbdev with block size equal in size with a core device.
We need to ensure that cache's bdev block size is not bigger than
core's bdev block size, so there are no IO errors due to IO length
smaller than cache device's block size.
The reason why this is implemented late in the cache start and not
as soon as we want to construct OCF vbdev is that cache or core
device can be added later after OCF vbdev creation and only then
we are certain to have both devices to compare.

According to this situation, we still use the MSG_ZEROCOPY

Furthermore, this new feature is dependent on the kernel
version, The currently verified version is
kernel 5.12 rc3. So it is not enabled in the default manner.

use the following rpc to configure:

7ec6d1d559 bdev/nvme: Read ANA log page itself when nvme_ctrlr is created
If ctrlr supports ANA log page, nvme_ctrlr allocates a buffer for ANA
log page and read ANA log page itself, and then each nvme_ns sets its
ANA state by parsing ANA log page.

Most code was brought from NVMe driver because NVMe driver already
supports ANA log page management. However it had a bug that assumed
each descriptor is 8-bytes aligned. Fix the bug together in this
patch. Besides, the implementation in NVMe driver was synchronous.
NVMe bdev module reads ANA log page asynchronously instead.

The next patch will support ANA log page update by AER handler.

c710c9acbe bdev/nvme: Rename nvme_io_path by nvme_ctrlr_channel
We will name the lower level objects starting with nvme_* and the
upper level objects starting with nvme_bdev_*.

This object is a channel per ctrlr and another new channel will be
added on top of this object.

Rename nvme_io_path by nvme_ctrlr_channel based on the new naming rule.

nvme_io_path will be used for a new object which is used to find an
optimal I/O path and to reset multiple ctrlrs sequentially when
multipath is supported.

1f433c4c32 bdev/nvme: prefer NGUID over UUID if supported
NVMe specification defines namespace identification descriptors i.e.
EUI64, NGUID, UUID.

BDEV abstracts NVMe specific details that is why only UUID is exposed,
however if NGUID is supported it is prefered to identify namespace
with NGUID over UUID.

If NGUID is not supported by NVMe Controller then fallback to UUID.

05dc895bea sock/posix: Fix the coredump when removing the sock from socks_has_data list
When entering the if case to order the list, there is bug should be
fixed. The original code does not address this.

The way this happens is when there is a connection left in the socks_with_data list
between polls and there are enough new events detected that it would exceed the
maximal number of events. A connection is left on this list between polls if it isn't
fully drained via reads by the upper layer on each poll loop.

Currently, the maximal socket event num is 32. Then we did not hit this issue
in our normal test cases. But when you use NVMe-oF tcp target to test which is
described in #2105, there are more than 32 active sockets, and it exceeeds
the maximal num of events of polling (32), so we will trigger this issue.

Fixes issue #2015

10808e45d4 idxd: refactor flow control for idxd engine
Recent work identified race conditions having to do with the
dynamic flow control mechanism for the idxd engine. In order
to both address the issue and simplify the code a new scheme
is now in place.  Essentially every DSA device will be allowed
to accomodate 8 channels and each channel will get a fixed 1/8
the number of work queue entries regardless of how many
channels there are.  Assignment of channels to devices is round
robin and if/when no more channels can be accommodated the get
channel request will fail.

The performance tests also revealed another issue that was
masked before, it's a one-line so is in this patch for convenience.
In the idxd poller we limit the number of completions allowed
during one run to avoid the poller thread from starving other
threads since as operations complete on this thread they are
immediately replaced up to the limit for the channel.

The reference count of nvme_bdev_ctrlr will be used to update ANA log
page safely, and nvme_bdev_ctrlr_destruct() can be used to decrement
reference count after completing ANA log page update.

However, nvme_bdev_ctrlr_destruct() is not a good name for this case.
Furthermore, nvme_bdev_ctrlr_destruct() does not set the destruct flag
to true, and the next patch will need nvme_bdev_ctrlr_acquire().

Hence rename nvme_bdev_ctrlr_destruct() by nvme_bdev_ctrlr_release().

Factor out registering nvme_bdev_ctrlr as io_device and populating

We extract spdk_io_device_register() from nvme_bdev_ctrlr_create()
because free(NULL) is correct but spdk_io_device_unregister(NULL) is
not allowed, and hence it is very simple if we call spdk_io_device_register()

However, after this patch, the controller will be detached when creating

fdc4c13e9e bdev/nvme: Rename nvme_io_channel by nvme_io_path
By the next patch, nvme_io_channel will be used as an I/O channel
to a single nvme_bdev. This channel is created to a single
nvme_bdev_ctrlr and has a corresponding I/O qpair. nvme_io_path
will be a better name especially when we support multipath.

5863f95ae4 bdev/nvme: Submit abort command for admin command on the current thread
Previously only a single thread could submit abort commands for admin
commands and it was the thread of the corresponding controller.

When we support multipath, we need to traverse the list of controllers
to which the target admin command is submitted. Threads of controllers
may be different.

On the other hand, the previous implementation made the I/O flow very
clean, but the I/O flow will not be clean if there are many controllers
and the subsystem does not have its thread.

This patch changes the policy so that any SPDK thread can submit abort
commands for admin commands.

Then when multipath is supported, we will be able to traverse the
list of controllers simply on the current thread to abort either I/O
command or admin command.

We already are able to submit any admin command on any thread anytime
including abort command. Hence this will not cause any issue.

We can put spdk_bdev_io_from_ctx(bio) into a parameter for a few

Passing not spdk_bdev_io but nvme_bdev_io to bdev_nvme_verify_pi_error()
remove unnecessary substitution.

64c6ddbf95 bdev/nvme: respond to attach RPC after bdev is examined
This makes use of newly added spdk_bdev_wait_for_examine(),
to only respond to RPC when bdev was fully examined.

Fixes #1760

Issue above was triggered in DD tests where application
finished before the examine had a chance to fully finish.
This patch addresses it by making sure that nvme attach
RPC waits for completion of the examine.
Later patch in series adds the bdev_wait_for_examine RPC
to multiple static configuration files. Making sure similar
issues do no occur for bdev modules which do not have changes
in their RPC as here.
The issue does not occur for JSON configs generated from apps,

f99d46d5f7 bdev/aio: move disk free operation in spdk_io_device_unregister's call back
Recently, checked the spdk_io_device_unregister function,
it will have deferred free behaviour, and the io_device
will possibly be freed in put_io_channel function.

And this means that it is not safe to directly call:
    spdk_io_device_unregister (io_device, NULL);
    Then free io_device relately resource.

Because there will be channel to use the resources associated
with io_device. Then we will possibly cause a NULL pointer access.

I found this issue in bdev rbd module, and I think that the
same issue could happen in other modules. So it is better to put the
resource free function as the call back function.

47c4304d83 subsystem/nvmf: remove cpu_mask hint when creating poll group
Passing cpu_mask hints that match only single core were
usefull to prevent any accidents when doing round-robin
in case of 'static' scheduler.
In practice this is not required in case of 'static' scheduler,
the threads will be spread out over all reactors anyway.

This hinders other schedulers which try to respect the cpu_mask
hints, as they would not move the thread to any reactor.
Preventing bunching up less used threads on single reactor.

Drawback of this patch is that poll group names will not match
the cores they are on.

3faf457f56 bdev/nvme: do not use DSM to emulate write zeroes
We cannot rely on DSM/DEALLOCATE as a write zeroes
alternative, even if DLFEAT reports that deallocated
blocks will be read as all zeroes.  DEALLOCATE is
advisory, meaning that blocks may not actually be
deallocated.  In cases where they are not deallocated,
they will not be read back later as zeroes.

QEMU 6.0 started reporting DLFEAT as returning zeroes
for deallocated blocks but for some of our write
zeroes tests, blocks aren't actually deallocated.

We may be able to add quirks in the future if we know
that a controller reliably deallocates blocks, but
for now we need to revert this completely.

Note that since bdev/nvme module now does not support
write zeroes in any cases, we need to disable the
write zeroes call in the unit tests.

Fixes issue #1932.

6cebe9d06b nvmf: Support physical block size if exposed by bdev
(Note: this patch was previously applied as b32cfc46 and then reverted
as 63642bef.)

Today the in-guest nvme device shows physical_block_size=512 even though
the backend iSCSI bdev supports physical_block_size=4K

iSCSI targets exposes physical block size using
logical_block_per_physical_block_exponent in READ_CAPACITY_16

NPWG is one of the way to let Linux nvme driver set
physical_block_size of the nvme block device.

This patch adds spdk_bdev.phys_blocklen which is updated if the iSCSI
backend exposes physical_block_size.
Later phys_blocklen is used in nvmf to set NPWG and NAWUPF to report
back during NS identity.
Linux driver uses min(nawupf, npwg) to set physical_block_size.

Similarly in scsi_bdev fill lbppbe in READ_CAP16 response
based on spdk_bdev.phys_blocklen.

365db9ee48 sock/posix: Deal with hung I/O with MSG_ZEROCOPY and interrupt
suppression

When all of the following conditions are met:
- non-blocking socket
- zero copy is enabled
- interrupts are suppressed (i.e. busy polling)
- NIC tx queue is full at the time sendmsg() is called
- epoll_wait sees there is already an EPOLLIN event
then we can get into a situation where data we've sent is queued
up in the kernel network stack, but interrupts have been suppressed
because other traffic is flowing. This makes the kernel miss the
signal to flush the software tx queue. If there wasn't also already
a pending EPOLLIN event, then epoll_wait would have been sufficient
to kick the system out of this state. But when all of this aligns,
it hangs.

We deal with this by detecting the scenario and calling poll(), which
will force the kernel to issue the pending transmits.

Hence bdev_nvme_reset() can call _bdev_nvme_reset() rather than
_bdev_nvme_reset_start() and store bio into nvme_bdev_ctrlr->reset_bio
after _bdev_nvme_reset() returns zero.

Then inline _bdev_nvme_reset_start() into _bdev_nvme_reset() because
_bdev_nvme_reset_start() has only a single caller now.

The following patches will introduce subsystem and bdev_nvme_reset()
will reset all controllers of a subsystem sequentially. These further

b1d6c2f3cb bdev/ocssd: Add ocssd_ns->depopulate_pending to complete pending depopulation
The following patches will remove nvme_ns->ref and use nvme_ns->populated
and nvme_ns->bdev instead because nvms_ns->ref is two at most and
each count of nvme_ns->ref corresponds to nvme_ns->populated or
nvme_ns->bdev.

To do that, we need to ensure nvme_ns->populated is cleared after
spdk_bdev_unregister() is called, otherwise nvme_bdev_ctrlr_destruct()
is called twice.

However OCSSD namespace had used nvme_ns->populated to free resource
after getting log page completes.

To keep such deferral, add the depopulate_pending flag to struct bdev_ocssd_ns
and use it. Then clear nvme_ns->populated in bdev_ocssd_free_namespace()
after spdk_bdev_unregister().

8cc81fa07a bdev/nvme: Inline nvme_bdev_ns_detach()
The nvme_ns->ref was added to nvme_bdev_ns to support both multipath
and OCSSD range. OCSSD range was to split a namespace into multiple
partitions.

However, OCSSD range was not used and removed to simplify multipath.

When namespace is not split, nvme_ns->ref is 2 at the maximum. First is
for populating namespace and second is for nvme_bdev. nvme_ns->populated
is for populating namespace and nvme_ns->bdev is for nvme_bdev.
Hence we can use nvme_ns->populated and nvme_ns->bdev directly instead of
nvme_ns->ref.

A few patches from this remove nvme_ns->ref and use nvme_ns->populated
and nvme_ns->bdev instead.

dThis patch inlines nvme_bdev_ns_detach() into the callers and remove it.

The following patches will adjust the locations to update nvme_ns->populated
and nvme_ns->bdev and then remove nvme_ns->ref.

Removing nvme_ns->ref will be helpful to associate multiple namespaces
into a single nvme_bdev for multipath.

610dd86b8c bdev/nvme: Inline nvme_bdev_ns_to_bdev() and remove it
nvme_bdev_ns_to_bdev() was introduced because nvme_ns->bdev may be
removed to support multipath. However, it is unlikely now.

Hence it is easier to read to stop using nvme_bdev_ns_to_bdev() and
access nvme_ns->bdev directly.

45d8309e52 bdev/nvme: Factor out deleting secondary trid into a helper function
Factor out deleting secondary trid from bdev_nvme_delete() into a
helper function bdev_nvme_delete_secondary_trid().

This will make the following changes simpler.

Besides, fix a typo, the case should be not 1B but 2B.

08e2210ace bdev/nvme: Merge callback and spdk_nvme_detach() into bdev_nvme_add_trid()
This change separates failover case more clearly, and will make
the following changes simpler.

Merge spdk_nvme_detach() and populate_namespaces_cb() into
bdev_nvme_add_secondary_trid(). Then change the return type of
bdev_nvme_add_secondary_trid() to void and move the comment to the
head of it.

0e3de45def bdev/nvme: Refactor add_trid() and rename it by add_secondary_trid()
Clean up bdev_nvme_add_trid() by factoring out comparison of namespaces
and comparison of trids into helper functions, bdev_nvme_compare_namespaces()
and bdev_nvme_compare_trids(), respectively.

Then rename bdev_nvme_add_trid() by bdev_nvme_add_secondary_trid().

Rename is for clarification and clean-up is for the next patch.
The next patch will merge spdk_nvme_detach() and populate_namespaces_cb()
into the renamed bdev_nvme_secondary_trid(). Clean-up makes the
next patch simpler.

One note is that checking if the type of trid is not PCIe is done
by holding mutex now to prioritize clean up.
