The QoS parameters are only used from the QoS thread,
so gather them together in a struct pointed to by the
bdev.

d7e065be93 blobstore: clone-snapshot blobstore relations
This commit provides an API to obtain an information about
snapshot and clone relations.

The main objective is:

 1) Determinate if we can delete snapshot (if have some created
    clones),

 2) Provide an information about parent/children nodes to the upper
    layer (e.g. lvol)

Realization:

 1) Structure parent-children is stored in the blob store object
    and updated on:

     a) blob store load,

     b) blob create/delete,

 2) Full information about parent-children is provided via new API:
    spdk_blob_get_parent() and spdk_blob_get_children(),

Note:

    While we don't store an information about these relations in the
    blob store, we need to open all blobs on blob store load to create
    it. It should be considered that it have an impact on the blobstore
    loading performance.

cbb8f46575 bdev: fix timing of init_complete callback
Recently added a new call to bdev modules to inform them of when
bdev subsystem init is complete. The intention is for modules like
RAID or crypto that need to take some action after the initial bdev
subsystem init such as 'build whatever RAID volumes you can, all
initial examine callbacks are done' or in the case of crypto 'OK,
construct all of your crypto structures for HW and SW PMDs and
associate each to configured vbdevs.'

Now that I've implemented the crypto case I see that the call was
misplaced and will execute following any examine_done call including
subsequent bdev registrations.  Those cases, for both RAID and crypto,
need to follow a different path (examine) since all of the activities
associated with the new init_complete() callback are intended just for
the very first initialization of SPDK.

So, long story short, moving this call so that it's only executed once
when subsystem init is done and not on subsequent bdev registrations.

3fa7c33ac1 nvme: require trid to be valid in nvme_ctrlr_probe
This is an internal NVMe driver function, so we don't need to allow for
the case where trid is NULL.  All callers already passed an address of a
local variable except the unit tests, which can be trivially fixed.

Fixes a static analyzer warning about trid being dereferenced in
nvme_transport_ctrlr_construct() before being checked for NULL in the
caller.

2931d638e7 bdev: Configure max_ios_per_timeslice when QoS is initialized
This value was recalculated on each time slice. Instead, just
set it up right away.

Right now QoS is statically configured at creation time for bdevs,
which means we can get away with this. Once dynamic
configuration is added, events will need to be sent to the QoS
thread.

Update the thread-local caches with new namespace data during each call
to spdk_nvmf_subsystem_remove_ns to handle the case where the user
requested to remove a namespace and then immediately add a different
one at the same namespace id. This makes the call asynchronous.

37039565d0 io_channel: add asserts in spdk_io_device_register
spdk_io_device_register() doesn't have a return value, but we can at
least catch trivial mistakes like neglecting to pass a valid io_device
or create/delete callback in debug builds.

One invalid unit test case that passed NULL for all parameters is
removed, since there's no way to make that work without adding a return
value instead of asserts.

a7aa9d5737 io_channel: ensure io_device is always freed just once
Imagine the following code flow:
1. `spdk_put_io_channel();`
2. `spdk_io_device_unregister();`

Since putting an io_channel is always deferred,
it is likely that spdk_io_device_unregister will
lock the io_channel mutex first. It will set
dev->unregistered flag and then quickly realize
there are still open channels for this device
(refcnt > 0) - so it'll return. All fine here.

However, if the deferred put_io_channel happens to
lock the mutex first from other thread, it will
decrement the refcnt and attempt to free the device.
Both the decrementation and freeing are done under
a mutex, but there is a slight window inbetween
where the mutex is re-locked. spdk_io_device_unregister
is already sleeping on a mutex_lock(), so it might
strike now. It'll see there are no more io_channels
for this device and free the device. Once
put_io_channels regains the lock again, it will attempt
freeing the device for a second time.

This patch removes the slight window mentioned above.

2e1dbc4587 bdev: Fix race condition when testing whether QoS is enabled
When testing whether QoS is enabled, the code previously
checked mutable values in the bdev itself. Instead, it needs
to check the flag in the channel.

Right now, QoS can only be configured statically when the
bdev is created. This means that no channels will exist
prior to QoS being turned on, which simplifies setting
the per-channel flag (only need to set it when a channel
is created).

This reverts commit 498f9add11bd439302f1a3d247b3f4c525696805.

Making the subsystem removal asynchronous seems to be triggering an

until we can diagnose the issue.

Performing a subsystem update on each poll group after the addition or
removal of a namespace allows us to avoid the case where we pause a
subsystem, perform a removal, then an addition, resume the subsystem and
don't update the channel for that subsystem. This, however requires that
spdk_nvmf_subsystem_remove_ns be asynchronous.
