acfb968aa8 bdev/nvme: avoid spdk_bdev_io_get_buf call when possible
The bdev layer nicely handles the case where we call this
function with the buffers already present - it just
immediately calls the get_buf_cb.  But this adds extra
overhead in the case where the buffer is already present.
Since nvme has no alignment restrictions, we can just
check the iovs directly and avoid the extra call to
spdk_bdev_io_get_buf when possible.

7deedab66a bdev/nvme: For writes, if there is only one iov element call
write instead of writev

Call spdk_nvme_ns_cmd_write_with_md if there is only one iov element.
Use spdk_nvme_ns_cmd_writev_with_md only if there is more than one.

This is about a 15% improvement in I/Ops.

3870092dd1 bdev/nvme: For reads, if there is only one element in the iov don't use
readv API

It's cheaper to call spdk_nvme_ns_cmd_read_with_md than it is to call
spdk_nvme_ns_cmd_readv_with_md, so do a quick check of the iovcnt and
use the best one for the job.

This is about a 15% improvement in I/Ops.

195fb4e40e bdev/aio: assign new io-ctx to each io-ch
It aims to avoid bdev starvation by setting separate
io_context to each bdev_aio io channel and link them
into group channel.

Previous, each ch of aio_bdev on a same spdk_thread shares
same io_context. If one of them submits too many IO to the
io_context, then other channels will be starved.
Moreover, if the first bdev_io gets NOMEM error, then the
following IO of this bdev have no chance to get processed.
The bdev_aio starvation can be reproduced by bdevperf in
v20.04, by:
./bdevperf -q 100 -w randwrite -t 5 -c hdd.conf -o 1048576
(hdd.conf defines 2 aio_bdevs of HDD)

aeb693ca07 bdev/gpt: Change ERRLOG to DEBUGLOG to show interleaved metadata is not supported
It is a good enhancement for the GPT vbdev module to support
interleaved metadata but interleaved metadata is not critical and
the priority is low.

However the following error log is always collected when there is
any bdev with interleaved metadata.

  vbdev_gpt.c: 552:vbdev_gpt_examine: *ERROR*: GPT module does not
    support block size 4224 for bdev Null0

This does not cause any failure but confuses user. Hence,  change
the corresponding print from ERRLOG to DEBUGLOG.

af4fa14891 module/bdev_raid: remove an ERROR log which occurs every times
This ERROR log is: bdev_raid_rpc.c: 276:rpc_bdev_raid_create: *ERROR*:
the rpc param strip_size is deprecated.
raid_bdev_write_config_json() generates a bdev.json:
    {
      "method": "bdev_raid_create",
      "params": {
        "name": "raid0",
        "strip_size": 64,
        "raid_level": "raid0",
        "base_bdevs": [
          "Malloc4",
          "Malloc5"
        ]
      }
    },

rpc_bdev_raid_create() will check this req.strip_size,
it always print this ERROR log:
else if (req.strip_size > 0 && req.strip_size_kb == 0) {
		SPDK_ERRLOG("the rpc param strip_size is deprecated.\n");

So I replace "strip_size" with "strip_size_kb" here.

1350922d09 bdev/ocf: take additional reference for ocf_cache
Fixes #1498

When shutting down the application, it was possible to
reference stale ocf_cache pointer. This was the case
when two or more vbdev_ocf devices were based on top
of single cache bdev.

This issue did not occur outside of the shutdown case,
since RPC only allows deletion of the vbdev_ocf.
This erases on disk metadata and next run of the application,
would not detect such vbdev_ocf.

Shutdown meanwhile works different, by first stopping
the instance of running "ocf_mngt_cache" and later detaching
"core" devices (the ones being cached). This prevented
erasing the on disk metadata and allowed for restarted
application to detect vbdev_ocf.
See patch (1292ef2) for details.

Since references to ocf_cache are copied between vbdev_ocf
[see start_cache()], the reference count inside ocf_cache
was limited to original ocf_mngt_cache_start() and
management queue creation. First call into ocf_mngt_cache_stop()
released all references to ocf_cache. Leaving other
vbdev_ocfs pointing to released memory.

This patch works around this issue by increasing ref cnt
on ocf_cache for each vbdev based on top of it.
It allows to call into ocf_mngt_cache_stop(), but not
release the memory for ocf_cache until last vbdev.

Note:
A proper redesign here is in order:
- either rearranging structures to be based around single ocf_cache,
rather than multiple vbdev_ocf instances
- better use of OCF API to reduce book keeping logic in vbdev

There are plans to implement detach/attach in RPC,
so it should be a focus during that effort.

868ba17780 bdev/ocf: simplify check for running cache instance
There are additional conditions which SPDK tracks,
that are known before issuing call to OCF.

Two main ones are:
- if vbdev->ocf_cache was not yet created [start_cache()]
- if the cache bdev was opened [attach_base()]

Both happen for the first cache bdev once. Then for
consecutive vbdev_ocf on same cache bdev, reference
will be copied.

This call will simplify checking both conditions.
Calling into OCF with NULL or stale ocf_cache pointer,
rightly so will cause issues with ASAN.

ee7e31f9ae lib/accel: remove the need for the app to allocate an accel_task
This was sort of a clunky interface requiring a couple of inline
functions in every app that wants to use the accel_fw moving
forward. By having the accel_fw public API accept a callback arg
instead of an accel_task combined with adding a pool of accel_tasks
in the accel_fw engine we can eliminate this.

After changing the parm to a cb_arg, changes were made to all accel_fw
interfaces to put cb_fn and cb_arg as the last parms in public and
private function calls.

Related bdev_malloc changes need to be in this patch in order to pass CI.

78f44434a6 lvol: report io_unit_size as block_size instead of page size
Bdev underneath lvs has a certain value set as block size,
then lvolstore inherits that as `io_unit_size`,
which ends up as block size for the lvol bdev presents.

Before this patch lvs on device with block size of 512,
would create lvol bdev with block size of 512.
Meanwhile reporting in bdev_lvol_get_lvstores(),
that block_size is 4k instead.

This was result of addition of io_unit_size and
forgetting to update the value here. Previously
only I/O of page_size was allowed.

This patch adjusts the value reported to
io_unit_size.

Alternatively it could have been removed,
or name changed to "io_unit_size".
Yet for API compatibility reason this name
remains.

Info on actual page size which is always 4k,
is not useful to bdev users. No need to add
another field for that.

47b0d4275c bdev/nvme: Support abort IO by using spdk_nvme_ctrlr_cmd_abort_ext()
Change NVMe bdev module to enable abort as IO type.

Change _bdev_nvme_submit_request() to process abort request when the
IO type is abort.

The current thread tries aborting I/O command in the I/O qpair first.
If no I/O command to abort was found, send message to the thread which
is registered when creating controller. The controller thread tries
aborting admin command in the admin qpair next. If no admin command
to abort was found, complete the abort request with failure.

spdk_nvme_ctrlr_cmd_abort_ext() is used to try aborting command whose
cb_arg matches. qpair is set to NULL when trying to abort admin command.

Before calling spdk_nvme_ctrlr_cmd_abort_ext(), save the current
thread to process admin command completion correctly.

spdk_bdev_abort() supports any bdev module other than NVMe bdev
module and does not check CDW0 but checks only if the completion
status is success or failure. So add bdev_nvme_abort_done() and
converts the NVMe completion status to the bdev completion status.
