It's not providing a lot of value, while being pretty problematic, as
the read is blocking and cannot be easily changed to be non-blocking, as
dump_info_json is a synchronous interface.
Now that dump_info_json isn't using any synchronous interfaces from the
NVMe driver, we can send a bdev_get_bdevs call in the async_init.sh
test to verify that.

This patch replaces the synchronous `spdk_nvme_detach()` calls with its
asynchronous counterparts in the controller unregister path.
An additional poller is introduced to periodically poll the NVMe driver
for detach completion. Once the detach is completed, the poller is
unregistered and the nvme_ctrlr is destroyed. The poller uses the same
period (1ms) as the async probe poller.
Since reset and detach cannot happen at the same time, reset_poller was
renamed to reset_detach_poller and it can now store the pointer either
to the reset or detach poller, depending on the circumstances.

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.

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.

Another idea is that poll group has a list of the associated bdev

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()

Hence include hostnqn into ctrlr_opts rather than passing it as a

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.

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.

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)

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.

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.
