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.

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.

c241161ad2 bdev/nvme: set default admin poll period to 10ms
Sending large amounts  of data from host to the controller with 1s
admin polling time, take a lot of time (e.g. 1M firmware file in 4k
chunks takes ~17min).

Reducing this time to 10ms whole operation takes about 3s.

ba7b55de87 bdev/nvme: do not destruct ctrlr if reset is in progress
The adminq poller could get a failure if the ctrlr has
already been hot removed, which starts a reset.

But while the for_each_channel is running for the reset,
the hotplug poller could run and start the destruct
process.  If the ctrlr is deleted before the for_each_channel
completes, we will try to call spdk_nvme_ctrlr_reset() on
a deleted controller.

While here, also add a check to skip the reset if the
controller is already in the process of being removed.

Fixes #1273.

The nvme_bdev_ctrlr.ref is now not only tracking the number of bdevs
created on that controller, but also the number of populated namespaces.

transport types. This change fills in the trstring so that downstream
checks correctly pass.

6db4a00c58 bdev/nvme: depopulate namespaces in module_fini callback
Currently the namespaces are depopulated in two cases: if the controller
is detached (either due to its hot unplug or RPC call) or due to
"namespace attribute changed" asynchronous event.  It means that during
shutdown, when nvme_bdev_ctrlr is destroyed, the namespaces aren't
depopulated.

For regular NVMe namespaces it isn't a big issue, since their only
depopulate task is to unregister bdevs created on that namespace, which
is already done by the bdev layer.  However, it can be a problem for
other types of namespaces (e.g. Open Channel), as they might allocate
their own context in nvme_bdev_ns.type_ctx, which, unless the namespace
is depopulated, cannot be freed.

This is a temporary solution that should be removed once bdev_ftl
becomes a virtual bdev and starts using bdevs instead of NVMe
controllers.

a116324c88 bdev/ocssd: initial Open Channel bdev implementation
This patch adds initial Open Channel zoned bdev implementation.  The
bdev will allow to use the zoned API on top of OCSSD devices.

Added the ability to create the OCSSD NVMe controller.  The controller
is created using the regular NVMe's RPC when the controller is detected
to be Open Channel.

f57b098e7c bdev_nvme: add synchronization to reset.
The generic bdev layer currently has a lot of snychronization built into
spdk_bdev_reset. However, in a couple patches I am going to introduce a
few instances where I call bdev_nvme_reset directly from this module.
The reason I call bdev_nvme_reset directly from this module is so that I
don't have to open a descriptor to the bdev in the module itself.

In order to be able to call bdev_nvme_reset from both this module and in
response to a bdev_io, we need to synchronize and queue reset requests.
