As the RBD bdev module does, the upper layer wants the reset command
to abort or complete all I/Os submitted before the reset command.
To satisfy this requirement, return all aborted I/Os by deleting I/O
qpairs to the upper layer without retry. To return all aborted I/Os
by deleting I/O qpairs, enable DNR for I/O qpairs. These I/O qpairs
are deleted and recreated. Hence, we do not have to disable DNR.
No more I/O comes at a reset I/O because the generic bdev layer already
blocks I/O submission. However, some I/Os may be queued for retry even
after deleting I/O qpairs. Hence, abort all queued I/Os for the bdev
before completing the reset I/O.

When I/O error resiliency is supported, most DNR parameters for internal

command, the upper layer wants the NVMe driver to return I/O errors
immediately without retry even if the upper layer enables I/O error retry.
To satisfy such requirement, add an abort_dnr variable to the spdk_nvme_qpair
structure and internal abort APIs use the abort_dnr variable. A public API
spdk_nvme_qpair_set_abort_dnr() can change the abort_dnr variable dynamically.

The llvm_precompile function checks for the CLANG version available on the machine

However, on the newest Fedora distribution, the path has changed and fuzzer libraries
couldn't be found. Currently, CLANG libraries path contains only major version number
(/usr/lib64/clang/16)
To address this issue, the function has been updated to search only for the major

the function now uses clang_num because in every Fedora distribution there is directory
or symlink that points to the right CLANG version.

As an lvolstore is being destroyed, _vbdev_lvs_remove() starts an
interation through the lvols to delete each one, ultimately leading to
the destruction of the lvolstore with a call to lvs_free(). The callback
passed to vbdev_lvs_destruct() is always called asynchronously via
spdk_io_device_unregister() in bs_free().
When the lvolstore resides on bdevs that perform async IO (i.e. most
bdevs other than malloc), this gives a small window when the lvol bdev
is not registered but a lookup with spdk_lvol_get_by_uuid() or
spdk_lvol_get_by_names() will succeed. If rpc_bdev_lvol_delete() runs
during this window, it can get a reference to an lvol that has just been
unregistered and lvol->blob may be NULL. This lvol is then passed to
vbdev_lvol_destroy().
Before this fix, vbdev_lvol_destroy() would call:
spdk_blob_is_degraded(lvol->blob);
Which would then lead to a NULL pointer dereference, as
spdk_blob_is_degraded() assumes a valid blob is passed. While a NULL
check would avoid this particular problem, a NULL blob is not
necessarily caused by the condition described above. It would better to
flag the lvstore's destruction before returning from
vbdev_lvs_destruct() and use that flag to prevent operations on the
lvolstore that is being deleted. Such a flag already exists in the form
of 'lvs_bdev->req != NULL', but that is set too late to close this race.
This fix introduces lvs_bdev->removal_in_progress which is set prior to
returning from vbdev_lvs_unload() and vbdev_lvs_destruct(). It is
checked by vbdev_lvol_destroy() before trying to destroy the lvol. Now,
any lvol destruction initiated by something other than
vbdev_lvs_destruct() while an lvolstore unload or destroy is in progress
will fail with -ENODEV.

The generic bdev layer has a fallback meachanism for the copy command
used when the backend bdev module does not support it. However, its max
size is limited. To remove the limitation, the fallback supports split by
using the unified split logic rather than following the write zeroes
command.
bdev_copy_should_split() and bdev_copy_split() use spdk_bdev_get_max_copy()
rather then referring bdev->max_copy to include the fallback case.
Then, spdk_bdev_copy_blocks() does the following.
If the copy size is large and should be split, use the generic split
logic regardless of whether copy is supported or not.
If copy is supported, send the copy request, or if copy is not
supported, emulate it using regulard read and write requests.

As name suffix, _done has been used more often than _complete for
fallback function names. 100 chars per line is suggested implicitly.
Do these small clean up in this patch.

Calculation of max copy size for fallback case includes division and is
costly. The result is constant for each bdev. Hence we can calculate it
only once and store it into bdev->max_copy at bdev registration.
Calculation of max copy size for fallback case is almost same as
calculation of max write zero size for fallback case. To reuse the
calculation, the helper function is named as bdev_get_max_write() and
has a num_bytes parameter.

The following patches will change spdk_bdev_register() to access iobuf
and bdev's blocklen and blockcnt.
Hence, we have to configure these correctly for alltest cases.
Move ut_init/fini_bdev() up in a file. Add missing ut_init/fini_bdev()
and allocate/free_bdev() calls for some test cases. Add blockcnt and
blocklen to allocate_vbdev().

As we recently fixed bdev_io_get_max_buf_len(), to get aligned length,
spdk_bdev_get_buf_align() - 1 is correct.
_bdev_get_block_size_with_md() considers both interleaved metadata and
separate metadata cases. It is simpler to use
_bdev_get_block_size_with_md().
The copy command fallback uses write command. As the write zeroes
fallback does, bdev->write_unit_size should be considered.
Fix all in this patch.

If spdk_spin_lock() is called on an uninitialized spinlock, it will
deadlock. This commit detects whether a lock is initialized and aborts
instead of deadlocking.

In debug builds, SPDK spinlocks will have stack traces that track where
they were allocated, last locked, and last unlocked. This adds gdb
pretty printers to make that information easily visible. See the updates
in doc/gdb_macros.md for details.
