Copy operation is defined by source and destination LBAs and LBA count
to copy. For destiantion LBA and LBA count we reuse exiting fields
`offset_blocks` and `num_blocks` in `struct spdk_bdev_io`. For source
LBA new field `src_offset_blocks` was added.
`spdk_bdev_get_max_copy()` function can be used to retrieve maximum
possible unsplit copy size. Zero values means unlimited. It is allowed
to submit larger copy size but it will be split into several bdev IOs.

Add a new parameter "-c" to display the per channel IO statistics
for required Bdev
./scripts/rpc.py bdev_get_iostat -b Malloc0 -h
usage: rpc.py [options] bdev_get_iostat [-h] [-b NAME] [-c]
optional arguments:
-h, --help show this help message and exit
-b NAME, --name NAME Name of the Blockdev. Example: Nvme0n1
-c, --per-channel Display per channel IO stats for specified device
This could give more intuitive information on each channel's processing
of the IOs with the associated thread on the same Bdev.
Please also be aware that the IO statistics are collected from SPDK
thread's related channel's information. So that it is more relating
to the SPDK thread. And in the dynamic scheduling case, different
SPDK thread could be running on the same Core.
In this case, any seperate channel's IO statistics are returned to
the RPC call and if needed, further parse of the data is needed to
get the per Core information although usually there is one thread
per Core.
On the other hand, user could run the framework_get_reactors RPC
method to get the relationship of the thread and CPU Cores so as
to get the precise information of IO runnings on each thread and
each Core for the same Bdev.

For write, verify DIF/DIX before submission and for read, verify
DIF/DIX after successful completion.
As same as the NVMe bdev module and the NULL bdev module, DIF/DIX
verification is done based on the DIF type and DIF insert/strip is
not supported.
In near future, the bdev I/O APIs bring an I/O flag to the underlying
bdev and the malloc bdev module will be able to decide DIF/DIX
verification based on the I/O flag.
One important feature is to setup protection information when
creating a malloc disk. Otherwise, all initial reads will fail
if protection information is enabled.
For users, add some explanation about the dif_type parameter

Different from the NULL bdev module, opts->block_size is a data block
size and a block size is caculated internally as a sum of
opts->block_size and opts->md_size if opts->md_interleave is true, or

opts->md_size accepts only either of 0, 8, 16, 32, 64, or 128.

NVMe-RDMA initiator will support SRQ in the following patches, and

get_rdma_qpair_from_wc() of NVMe-RDMA target uses wc->qp_num internally

Hence, it will be convenient to pass WC instead of qp_num if we consider

nvme_rdma_ctrlr_disconnect_qpair() does not poll the qpair until it is
actually disconnected if it is in a poll group even if its async mode
is disabled. Hence, spdk_nvme_ctrlr_free_io_qpair() removes the qpair
from a poll group when it is being disconnected.
On the other hand, I/O qpair is destroyed after it is actually
disconnected.
When SRQ is enabled and used, a SRQ is destroyed if the corresponding
poller does not have any I/O qpair after an I/O qpair is removed from
the poller.
In particular, if we use spdk_nvme_ctrlr_free_io_qpair(), a SRQ is
destroyed before the corresponding I/O qpairs are destroyed.
Destroying a SRQ failed because it is still referenced by I/O qpairs.
This bug was found when running the SPDK NVMe perf tool with SRQ.
The reason was we had nvme_rdma_poll_group_process_completions() to call
disconnected_qpair_cb after the qpair is actually disconnected.
However, it is ensured that nvme_rdma_poll_group_process_completions()
calls disconnected_qpair_cb for any disconnected qpair.
Hence, remove a check if qpair->poll_group is not NULL from
nvme_rdma_ctrlr_disconnect_qpair() and update the comment.

With RDMA, the admin poller can experience a remote disconnect when

this. The disconnect code path will manually complete queued aborts.
However, the completion callback for the abort will attempt to resubmit
other queued aborts from the queue, which will result in a very large
stack and can eventually cause a segfault.
The fix is to not resubmit queued aborts if the admin qpair is in any

To support SQs allocated to a poll group other than the controller's
main poll group, we need to make sure to poll those SQs when we wake up
and handle the controller interrupt. As they will be running in a
separate SPDK thread, we will arrange for all poll groups to wake up
when we receive an interrupt corresponding to a vfio-user message
arriving.
This can mean needless wakeups: we don't (yet) have a mechanism to only
wake up the poll groups that correspond to a particular SQ write.
Additionally, as we don't have any notion of a poll group per
controller, this ends up polling all SQs in the entire poll group, not
just the ones corresponding to the controller we were handling.
As this has potential performance issues in many cases, it defaults to
disabled.

CRC op writes the value into *op->crc_dst
UNLESS it is NULL.
The problem is that _idxd_prep_batch_cmd() that allocates
new ops left op->crc_dst uninitialized.
This results in a memory corruption (use after free)
in the following scenario:
1) op A is allocated an crc_dst is set to point to user memory X.
2) Op A is compeleted
3) User memory X is freed.
4) Ops B and C are allocated (chained), C has crc_dst set.
=> B reused op A memory and crc_dst still points to the
now stale user location (1)
5) B is complered, spdk_idxd_process_events() writes into X
as B->crc_dst = X.
Fix: _idxd_prep_batch_cmd() should initialize crc_dst to NULL.

We were missing a check when ISAL uses the complete output buffer
on compression to determine whether it was s perfect fit or if
simply not enough buffer was provided.

Do not run test with message send using hello_sock client with
KTLS enabled. CI does not have systems that run with openssl-3
and KTLS and it fails under Fedora36.
This test should be brought back after systems do run openssl-3
on board.

Prevent user from switching back to static scheduler after
different scheduler has been selected. Currently we
do not have a way to save initial thread distribution
configuration, so each time user switches from dynamic
scheduler back to static, the SPDK threads may end up on
different reactors. This would cause discrepancy in
performance statistics of SPDK managed by static scheduler.
