A host will consider a QID as reusable once it disconnects
from the target. But our target does not immediately
free the QID's bit from the ctrlr->qpair_mask - it waits
until after a message is sent to the ctrlr's thread.
So this opens up a small window where the host makes
a valid connection with a recently free QID, but the
target rejects it.
When this happens, we will now start a 100us poller, and
recheck again. This will give those messages time to
execute in this case, and avoid unnecessarily rejecting
the CONNECT command.
Tested with local patch that injects 10us delay before
clearing bit in qpair_mask, along with fused_ordering
test that allocates and frees qpair in quick succession.
Also tested with unit tests added in this patch.

spdk_iov_sgl_init doesn't advance iovs, as result
when we do sgl->iov->iov_len - sgl->iov_offset,
we may get unsigned int underflow.
Fix is init sgl with 0 offset and then advance it

As the blobstore is being unlaoded, async esnap channel destructions may
be in flight. In such a case, spdk_bs_unload() needs to defer the unload
of the blobstore until channel destructions are complete.
The following commands lead to the illustrated states.
bdev_malloc_create -b malloc0
bdev_lvol_clone_bdev lvs1 malloc0 eclone
.---------. .--------.
| malloc0 |<--| eclone |
`---------' `--------'
bdev_lvol_snapshot lvs1/eclone snap

bdev_lvol_clone lvs1/snap eclone
.--------.
,-| eclone |
.---------. .------.<-' `--------'
| malloc0 |<--| snap |
`---------' `------'<-. .-------.
`-| clone |
`-------'
As the blobstore is preparing to be unloaded spdk_blob_unload(snap) is
called once for eclone, once for clone, and once for snap. The last of
these calls happens just before spdk_bs_unload() is called.
spdk_blob_unload() needs to destroy channels on each thread. During this
thread iteration, spdk_bs_unload() starts. The work performed in the
iteration maintains a reference to the blob, and as such it
spdk_bs_unload() cannot do its work until the iteration is complete.

The channel passed to blob IO operations is useful for tracking

resides on. Esnap clone blobs perform reads from other bs_devs and
require per-thread, per-bs_dev channels.
This commit augments struct spdk_bs_channel with a tree containing
channels for the external snapshot bs_devs. The tree is indexed by blob
ID. These "esnap channels" are lazily created on the first read from an
external snapshot via each bs_channel. They are removed as bs_channels
are destroyed and blobs are closed.

it's also fine to just not increment it at the

2) Add blob_verify_md_op() calls, just to be sure
these are only called from md_thread. This was
already checked in calling functions, but as these
functions get called from new code paths (i.e.
esnap clones) it can't hurt to add additional
checks.
3) Add unit test that failed with original code, but
passes with this patch.
Fixes issue #2935.

It is quite common for a user to use the exact same iovec (in memory) to
describe buffers for two different operations. If that iovec was
describing accel buffer, accel would modify it replacing it with an
actual buffer. This is broken if that iovec was used by some other task
in a sequence, as accel wouldn't be aware that it has been changed too.
To address this, accel will use a new iovec from the aux_iovs array. It
means that accel buffers always *must* be passed using a single iovec.
Theoretically, users could chunk that buffer into several iovecs, but
spdk_accel_get_buf() always returns a single buffer, so, in practice,
this should never happen, and therefore is unsupported.

It is now possible to submit a write request with a sequence of accel
operations that need to be executed before actually writing the data.
Such requests will be directly passed to a bdev module (so that it can
append subsequent operations to an accel sequence) if that bdev supports
accel sequences and the request doesn't need to be split. If either of
these conditions are not met, bdev layer will execute all the
accumulated accel operations before passing the request to a bdev
module.
The reason for not submitting split IOs with an accel sequence is that
we would need to split that accel sequence too. Currently, there's no
such functionality in accel, so we treat this case in the same way as if
the underlying bdev module didn't support accel sequences (it's executed
before bdev_io is split).

This is the beginning of support for external snapshots. An external
snapshot is a read-only blobstore device (struct spdk_bs_dev) that can
be used as a blob's back device. Normally a blob will have no back
device (a normal blob), a zeroes back device (a thin provisioned blob),
or a blob back device (a clone blob). When a blob has an external
snapshot ("esnap") as its back device, it is called an esnap clone.
With this patch, esnap clones can be created but they are not yet
useful. Subsequent patches in the series will plumb the IO path, enable
various features, and allow lvol bdevs to be esnap clones.

If a driver is registered and selected, it'll now be used to execute
sequences of accel operations. The driver has priority over accel
modules, so the modules will only be used to execute operations that the
driver cannot perform.
Once driver completes a task (or a number of tasks), it notifies accel
using standard spdk_accel_task_complete(). To let accel continue
processing a sequence, driver can call spdk_accel_sequence_continue().
This can be done when the driver executes all tasks (1), an error occurs
(2), or the driver doesn't know how to execute a given opcode (3). In
case of (3), that operation will be executed using appropriate accel
module and, while the rest of the sequence will be sent back to the

The spdk_bdev_ext_io_opts structure is used to pass extra options when
submitting a bdev IO request, without having to modify/add functions to
handle new options. Additionally, the structure has a size field to
allow adding new fields without breaking the ABI (and thus having to
bump up the major version of a library).
It is also a part of spdk_bdev_io and there are several reasons for
removing it from that structure:
1. The size field only makes sense in structures that are passed
through pointers. And spdk_bdev_ext_io_opts is indeed passed as a
pointer to spdk_bdev_{readv,writev}_blocks_ext(), however it is
also embedded in spdk_bdev_io (internal.ext_opts_copy), which is
also part of the API. It means that each time a new field is added
to spdk_bdev_ext_io_opts, the size of spdk_bdev_io will also
change, so we will need to bump the major version of libspdk_bdev
anyway, thus making spdk_bdev_ext_io_opts.size useless.
2. The size field also makes internal.ext_opts cumbersome to use, as
each time one of its fields is accessed, we need to check the size.
Currently the code doesn't do that, because all of the existing
spdk_bdev_ext_io_opts fields were present when this structure was
initially introduced, but we'd need to do check the size before
accessing any new fields.
3. spdk_bdev_ext_io_opts has a metadata field, while spdk_bdev_io
already has u.bdev.md_buf, which means that we store the same thing
in several different places in spdk_bdev_io (u.bdev.md_buf,
u.bdev.ext_opts->metadata, internal.ext_opts->metadata).
Therefore, this patch removes all references to spdk_bdev_ext_io_opts
from spdk_bdev_io and replaces them with fields (memory_domain,
memory_domain_ctx) that were missing in spdk_bdev_io. Unfortunately,
this change breaks the API and requires changes in bdev modules that
supported spdk_bdev_io.u.bdev.ext_opts.

This implements the v2 claims API. Compared to the original v1 claims,
v2 claims:
- Support read-write-once, read-write-many, and read-only-many claims.
- Are claimed with spdk_bdev_module_claim_desc().
- Are associated with a bdev descriptor that is passed to
spdk_bdev_module_claim_bdev_desc().
- Are released upon close of the bdev descriptor used to obain the
claim.
- Cannot be taken when a descriptor other than the one passed to
spdk_bdev_module_claim_bdev_desc() has write access.
Later commits in this series are needed to fully integrate them with the
bdev subsystem.

Make vbdev_crypto_destruct() return 1 to signal that program
execution should wait for spdk_bdev_destruct_done() function,
which is added inside _device_unregister_cb().
This change is related to _vdev_dev_get() not being able
to find the devices, when called from _cryptodev_sym_session_free(),
as it uses device driver name, which might already be freed.
This occurs only during bdev module finish, when crypto bdevs
are being unregistered and vbdev_crypto_finish() proceeds to
call bdev name deletion without waiting for the unregister
callbacks to complete, which ultimately results in reading
freed pointers.
This only happens when code execution takes path for DPDK 22.11+.

This patch support IO stat for nvme_io_path. Record each nvme_io_path
stat using structure spdk_bdev_io_stat.

1 Null bdev: block size: 4K, num_blocks:16k
run bdevperf with io size=4k, qdepth=1/32/128, rw type=randwrite/mixed with 70% read/randread
Each time run 30 seconds, each item run for 16 times and get the average.
