97a5ea5796 lib/bdev: spdk_bdev_abort supports I/O splitting
The last patch ensures that the parent I/O terminate with failure
before continuing splitting process if one of child I/O failed.
This simplifies abort operation for I/O splitting.

Then we can use bdev_abort() and bdev_abort_io() nestedly.

Add necessary unit test together.

089d178abb lib/bdev: Terminate parent I/O with failure immediately if one of child I/O failed
Previously, bdev_io_split_done() had continued splitting process
even if the status became failed. To abort split I/O, this patch
changes bdev_io_split_done() to terminate with failure before
continuing splitting process if the status became failed. Add
necessary unit test together.

29f86a2630 lib/bdev: spdk_bdev_abort supports queued I/O due to buffer allocation
Buffer allocation is done after redirection to the QoS thread.
Hence add a new helper function bdev_abort_queued_io() and add
its call to bdev_io_do_submit() for both buf_need_small and
buf_need_large.

For zcopy API, buffer allocation is done before buffer allocation
but the caller can get bdev I/O object, and can abort the I/O
directly if needed.

0d31e2bae6 lib/bdev: spdk_bdev_abort supports queued I/O due to out of memory
Add abort queued I/O due to out of memory into bdev_io_do_submit().
Any bdev I/O is queued due to out of memory only on the submitted
channel.

Aborting queued I/O due to out of memory is necessary only if
shared_resource->nomem_io is not empty.

Checking if shared_resource->nomem_io is not empty has been done
in this function.

However add the abort operation without and before checking if
shared_resource->nomem_io is not empty because the following patch
will abort queued I/O due to buffer pool capacity.

The purpose is to improve readability by consolidating all abort
operations into a single place.

f048f3d3d3 lib/bdev: spdk_bdev_abort supports the case when QoS is enabled
When the target I/O is controlled by QoS, the abort request is
submitted on the same channel that the target I/O is submitted.

By using this, add a helper function bdev_abort_queued_io(), and
change _bdev_io_submit() to call bdev_abort_queued_io(), and
call _bdev_io_complete_in_submit() with success if bdev_abort_queued_io()
returned true when QoS is enabled on the corresponding channel.
Add necessary unit test together.

Update unit test accordingly, especially, update stub_submit_request()
to abort the matched I/O, update io_during_io_done() because we need to
know not boolean but the exact completion status now, and update
basic_qos() to reset the rate limit to test the abort I/O feature.

5771019fc0 lib/bdev: Factor out bdev I/O complete operation in _bdev_io_submit()
The following patch will add another spdk_bdev_io_complete() call
in _bdev_io_submit(). Then, factoring out set/clear in_submit flag,
incrementing counts and calling spdk_bdev_io_complete() into a helper
function will be simpler.

in_submit flag is set and clear in bdev_io_do_submit() anyway,
and bdev_qos_io_submit() needs in_submit flag only for
bdev_io_do_submit().

All cases to call spdk_bdev_io_complete() in _bdev_io_submit() are
not performance critical.

8889f7b7f4 lib/bdev: Add SPDK_BDEV_IO_STATUS_ABORTED to notify the upper layer correctly
The I/O aborted by the abort command should be completed with SC = 07h, i.e.,
"Command Abort Requested". However, if the generic bdev layer or non-NVMe
bdev module aborted the I/O, the aborted I/O would complete with SC = 06h, i.e.,
"Internal Error". To fix this unexpected behavior, add an new I/O status
SPDK_BDEV_IO_STATUS_ABORTED and update spdk_bdev_io_get_nvme_status() to
set SC to 07h if the I/O status is SPDK_BDEV_IO_STATUS_ABORTED.
If the NVMe bdev module aborts the I/O, the I/O status is set to
SPDK_BDEV_IO_STATUS_NVME_ERROR and SC is set as expected.

7cd20dd3f5 lib/bdev: Add spdk_bdev_abort API
Add spdk_bdev_abort function as a new public API.

This goes all the way down to the bdev driver module and attempts to
abort all I/Os which has bio_cb_arg as its callback argument.

We can separate when only a single I/O has bio_cb_arg and when multiple
I/Os have bio_cb_arg, but unify both by using parent - children I/O
relationship. To avoid confusion, return matched_ios by _bdev_abort() and
store it into split_outstanding by the caller.

Exclude any I/O submitted after this abort command because the same cb_arg
may be used by all I/Os and abort may never complete.

bdev_io needs to have both bio_cb_arg and bio_to_abort because bio_cb_arg
is used to continue abort processing when it is stopped due to the capacity
of bdev_io pool, and bio_to_abort is used to pass it to the underlying
bdev module at submission. Parent I/O is not submitted directly, and is
only used in the generic bdev layer, and parent I/O's bdev_io uses bio_cb_arg.
Hence add bio_cb_arg to bdev structure and add bio_to_abort to abort structure.

In the meantime of abort operation, target I/Os may be completed. Hence
check if the target I/O still exists at completion, and set the completion
status to false only if it still exists.

Upon completion of this, i.e., this returned zero, the status
SPDK_BDEV_IO_STATUS_SUCCESS indicates all I/Os were successfully aborted,
or the status SPDK_BDEV_IO_STATUS_FAILED indicates any I/O was failed to
abort by any reason.

spdk_bdev_abort() does not support aborting abort or reset request
due to the complexity for now.

Following patches will support I/O split case.

Add unit tests together to cover the basic paths.

Besides, ABI compatibility check required us to bump up SO version of
a few libraries or modules. Bump up SO version of blob bdev module simply
because it does not have any out-of-tree consumer, and suppress bumping
up SO version of lvol library because the affected struct spdk_lvol
is not part of public APIs.

This is an important aspect of ABI versioning.

There was a change to the spdk_bdev_opts struct
which is accessible from the public API that results
in an ABI change.

There was also a change in the spdk_accel_module_if struct that
will affect new modules so its major version needs to be revved.

There was also a change in the publically accessible rmda_hooks
structure which forced an ABI change in the NVMe library.

dc3717296e bdev: handle unlock v. lock race
When we unlock a range, we remove the range from the
locked bdev list before doing the for_each_channel
iteration to remove the range from each channel.

But at the same time, right after removing from the
locked list, a new lock on that range could start.
In that case, we also do a for_each_channel to add
the range to each channel, and that will race with
the for_each_channel remove.  When the lock start
wins, it finds the range already in the channel,
but doesn't set the owner_range which results in
a seg fault when the for_each_channel completes.

The fix is actually rather simple.  We just add the
locked_ctx to the comparison when checking if the
range is already in the channel.  If the locked_ctx
matches, then we know it was added as part of
initializing a new channel.  If it doesn't, then
we create a new range object pointing to the new
locked_ctx.  The first one will get removed when
the remove for_each_channel catches up.

82a4c84fec lib/bdev: Add support for new per bdev_io auxiliary buffer.
A new API was added `spdk_bdev_io_get_aux_buf` allowing the caller to request
an auxiliary buffer for its own private use. The API is used in the same manner that
`spdk_bdev_io_get_buf` is used and the length of the buffer is always the same as the
bdev_io primary buffer.  'spdk_bdev_io_put_aux_buf' is called to free the
auxiliary buffer.

The initial use case is crypto, in the next patch in series it is used. No UT were
added as the logic isn't that complicated and it is fully tested with each run
of crypto.

Fixed a comment typo also (not mine for once).

b90b7ce477 bdev: queue new IO that overlap a locked region
Add an io_locked TAILQ to each channel, which hold
IO that will write to a currently locked region.

Also add a new step to the locking process per channel.
Each channel needs to wait until all existing outstanding
writes to the newly locked range have been completed.

Only the channel that locked an LBA range may submit
write I/O to it.  It must use the same cb_arg for the
write I/O as the cb_arg used when locking the LBA range.
This ensures that only the specific I/O operations needing
the lock will bypass the lock.

When a range is unlocked, we will just blindly try to
resubmit all IO in the io_locked tailq.  This could be
made more efficient in the future, but we don't expect
this path to occur very often, so going for simplicity
in the first pass.

b9af5dd834 lib/bdev: batch queued bdev reset completions.
Previously, when additional resets were submitted while a reset was in
progress, those resets were queued and then executed serially as part of
executing the original reset. Doing multiple resets on a bdev in quick
succession is not useful if the first reset succeeds and is very
unlikely to be useful in the negative case. Instead, we should batch
resets and complete them all at once when the current reset succeeds or
fails.
