Patch 55f947933 ("bdev: remove spdk_bdev_ext_io_opts from spdk_bdev_io")
changed the way bdev_nvme submits IO to the NVMe driver causing
performance degradation for requests with iovcnt = 1, as they also had
to go through the path that executes the reset_sgl/next_sge callbacks.
This patch reverts those changes back to the original code checking
iovcnt and using the non-SGL functions if possible.

`rpc_bdev_lvol_resize` and `rpc_bdev_lvol_create` can now use size
in MiB instead of `size` in bytes. This change make param `size`
deprecated and using both `size` and `size_in_mib` return error.
Since `bdev_lvol_resize` and `bdev_lvol_create` use size in MiB,
name of param should reflect it, previously used param `size` is
positional therefore there is no need to keep it as deprecated.

Factor out path deletion operation for one nvme_ctrlr into _bdev_nvme_delete().
_bdev_nvme_delete() traverses all remaining nvme_ctrlrs even after one
nvme_ctrlr was successfully deleted. To remember the successfule
deletion, use two return value variables, rc and _rc. For _rc returned by
_bdev_nvme_delete(), copy _rc to rc if _rc is zero, return _rc immediately
if _rc is not -ENXIO, or do nothing otherwise.
This improves the readability and makes us easier to add more changes.
Additionally, for _bdev_nvme_reset_io(), it is simpler to overwrite rc
to 0 if rc is -EBUSY rather than to return 0 if rc is -EBUSY. This is
very small change and hence done together.

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.

than replacing these by spdk_for_each_bdev(). Additionally, not only
spdk_bdev_close() but also spdk_put_io_channel() and
spdk_jsonrpc_send_*_response() should be done on the original thread.
Hence, redirect to the original thread always when a NVMe command is

clarification. orig_thread will be better than comment.

The gpt bdev module has an off-by-one error. When it

We cannot just fix it by changing the math here, any
consumers of the partition may have put down metadata
on the partition based on the old size.
So instead add a new SPDK partition type. SPDK will keep
the existing off-by-one behavior when it finds the old
partition type, but will use the correct math when finding
the new partition type.

To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.
Increasing major so version after LTS, allows the future releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.
Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 23.05
release.
Looks like this was left over from prior LTS, to avoid that
make sure it is only skipped when running against v23.01.x as latest
release.
This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests
Short reference to how the versions were changed:
MAX=$(git grep "SO_VER := " | cut -d" " -f 3 | sort -ubnr | head -1)
for((i=$MAX;i>0;i-=1)); do find . -name "Makefile" -exec \

This is the port of the vbdev compress logic into the accel
framework. It includes just one enhancement, to only fill each
mbuf in either src or dst array with max "window size" param to
avoid QAT errors. Note that DPDK ISAL PMD was not ported as we
have native ISAL compression in accel now.
Note: ISAL w/DPDK is still built w/this patch, that can't be
removed until the vbdev module moves to accel fw as it still
depends on DPDK ISAL PMD.
Follow-on patches will include addition C API for PMD selection,
this patch just gets equivalent functionality going. Upcoming
patches will also convert the vbdev compress module to use the
accel framework instead of talking directly to compressdev.
More patches will also address comments on vbdev common code
that addressed here would make the review challenging.
This patch also fixes a bug in the ported code that needs to
be fixed here to pass CI. Capability discovery was incorrect
causing all devices to appear to not support chained mbufs,
with the mbuf splitting code this is important to get right.

It doesn't appear there is any easy way to use the avahi

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+.

Currently delete_crypto_disk() calls spdk_bdev_unregister_bdev_by_name()
and immediately after exiting that function, it proceeds to bdev name
deletion. This causes callbacks triggered by above call to run with
references to bdev names that are partially unavailable due to free()
functions in vbdev_crypto_delete_name().
Add an intermediate callback that will call vbdev_crypto_delete_name()
and then the original callback that was sent as an argument to
delete_crypto_disk(). That way we are sure that bdev name deletion
is performed right after bdev unregister.

Currently we have stat per bdev I/O channel, but for NVMe bdev
multipath, we don't have stat per I/O path. Especially for
active-active mode, we may want to observe each path's statistics.
This patch support IO stat for nvme_io_path. Record each nvme_io_path
stat using structure spdk_bdev_io_stat.
The following is the comparison of bdevperf test.
Test on Arm server with the following basic configuration.
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.
The result is as follows.

Implement the resize function for RAID0. raid0_resize() calculate the
new raid_bdev's block count and if it is different from the old block
count, call spdk_bdev_notify_blockcnt_change() with the new block count.
A raid0 bdev always opens all base bdevs. Hence, if the size of base
bdevs are reduced, resize fails now. This limitation will be removed
later.
Add a simple functional test for this feature. The test is to create
a raid0 bdev with two null bdevs, resize one null bdev, check if the
raid0 bdev is not resize, resize another null bdev, check if the raid0
bdev is resized.
test/iscsi_tgt/resize/resize.sh was used a reference to write the test.
Using jq rather than grep&sed is better and hence replace grep&sed by jq
of test/iscsi_tgt/resize/resize.sh together in this patch.
