56d8cc8d72 bdev/ocssd: Process only the head of nvme_ns->bdevs
The range parameter was deprecated from bdev_ocssd_create(), and
hence one ocssd_bdev can be created per one ocssd_ns now.
Hence process only one ocssd_bdev per one ocssd_ns. The following
patches will replace a linked list nvme_ns->bdevs by a pointer
nvme_ns->bdev.

e4070ee0e0 so_ver: increase all major versions
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 quarterly 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 21.04
release.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

Fctor out getting nvme_ns and qpair pointers in _bdev_nvme_submit_request()

ocssd_bdev needs not spdk_nvme_ns but nvme_bdev_ns pointer in I/O paths,

Besides, move inclusion of likely.h from bdev_nvme.c and bdev_ocssd.c

The next patch will apply bdev_nvme_find_io_path to ocssd_bdev.

By the following patches, bdev_nvme_find_io_path() will take ANA

acf116c6d5 bdev/nvme: run poller more frequently while probe in progress
When we do detect new devices, we would like to get them
attached as quickly as possible. Controller initialization
requires a non-trivial number of admin commands, and when
using async probe, it means that after we have detected
a new device, it will take many iterations of calling
spdk_nvme_probe_poll_async() before the controller is
fully attached.

So when we are actively probing a probe_ctx, create
a new poller that is solely responsible for probing
that context at a much higher frequency.

nvme_bdev_ctrlr pointer is already cached to nvme_io_channel.
Hence let's remove it from the helper functions, bdev_nvme_create_qpair()

The following minor fixes are done together in this patch.

Fix the error paths of bdev_nvme_create_qpair() because
bdev_nvme_destroy_qpair() cannot be used as is in this case.

When calling bdev_ocssd_destroy_io_channel(), check if nvme_ch->ocssd_ch
is not NULL instead of spdk_nvme_ctrlr_is_ocssd_supported().

Cache nvme_bdev_ctrlr to nvme_io_channel just before calling
bdev_nvme_create_qpair() because the pointer is more associated
with qpair.

17afd268df nvme: call correct remove_cb when device is removed
When a device is removed, we should use the remove_cb
that was specified when the device was originally probed
and attached, if one was set.

Also add a new spdk_nvme_ctrlr_set_remove_cb API.  This
can be used for cases where a different remove_ctx is
desired than was specified for the probe call.  This
also enables setting a remove_cb when using connect APIs
which do not have a way currently to provide a remove_cb.

This also requires fixing the bdev nvme module, which
was depending on the previously errant behavior.

Fixes issue #1715.

It is recommended to read CSTS when there is a timeout.
If CSTS.CFS (Controller Fatal Status) is set, we should

But if an admin command on a fabrics controller times
out, reading CSTS submits another fabrics command that
could also timeout.  Even worse, we are recursively
polling the admin queue for completions in this case.

db436f2dc0 bdev/nvme: Refactor namespace comparison in add_trid()
In other places, nvme_ns->populated has been used to check an namespace
is active for an existing nvme_bdev_ctrlr. We do not need to call
spdk_nvme_ctrlr_is_active_ns() again. Follow it in this patch.

Besides, factor out the namespace comparison into a small helper
function bdev_nvme_compare_ns(). It will be used to check if two
controllers have the common namespace for ANA multipath.

f85b860d27 bdev/nvme: Add failover trid to an existing ctrlr in the attach callback
Previously, we separated two cases, creating an new nvme_bdev_ctrlr
and adding an new path to an existing nvme_bdev_ctrlr as early as
possible.

However, we can merge creating an new connection between these two
cases. In this patch, connect_attach_cb() calls bdev_nvme_add_trid()
and then calls spdk_nvme_detach() if the nvme_bdev_ctrlr whose name is
ctx->base_name already exists.

This will simplify ANA multipath feature.

bd65fef240 bdev/ocssd: Add ocssd_bdev parameter to I/O submit functions
nvme_bdev passes not spdk_bdev_io but nvme_bdev_io pointer to I/O
submit functions, and gets spdk_bdev_io pointer from nvme_bdev_io
pointer in its completion callback functions.

This is very clean because spdk_bdev_io is processed by the generic bdev
layer and nvme_bdev_io is processed by the NVMe bdev module.

The patch series changes ocssd_bdev to pass not spdk_bdev_io but
bdev_ocssd_io pointer to its I/O submit functions.

This patch is the first of the series and add ocssd_bdev parameter
to I/O submit functions. ocssd_bdev pointer is got from
bdev_io->bdev->ctxt. Hence this patch removes one dependency on
spdk_bdev_io.

One noticeable small change is that get_zone_info() gets zone_info
from not bdev_io->bdev but nvme_bdev->disk to advance removing
the dependency on spdk_bdev_io.

01f769c62a bdev/nvme: Ensure ctrlr->destruct is set only once
Checking if destruct is false and setting destruct to true are
separated by mutex in remove_cb() and bdev_nvme_library_fini().

It was possible that multiple threads called nvme_bdev_ctrlr_destruct()
because the caller could call nvme_bdev_ctrlr_destruct() before
setting destruct to true after knowing it was false.

This patch ensures that nvme_bdev_ctrlr_destruct() is called only once.

Set ctrlr->destruct to true without releasing mutex after checking
if ctrlr->destruct is false.

If destruct is set to true before calling nvme_ctrlr_depopulate_namespaces(),
nvme_ctrlr_depopulate_namespace_done() may call nvme_bdev_ctrlr_destruct()
because it is likely that reference count is zero and destruct is true.
In this case, remove_cb() or bdev_nvme_library_fini() cannot call
nvme_bdev_destruct() after returning from nvme_ctrlr_depopulate_namespaces().

On the other hand, if a controller has no namespace,
nvme_ctrlr_depopulate_namespaces() does nothing and
nvme_ctrlr_depopulate_namespace_done() is not called. Hence
remove_cb() or bdev_nvme_library_fini() has to call nvme_bdev_destruct()
after returning nvme_ctrlr_depopulate_namespaces().

To unify both cases, initialize reference count to one as a sentinel value
and remove_cb() and bdev_nvme_library_fini() decrement reference count
and then calls nvme_bdev_ctrlr_destruct() if reference count is zero
after returning from nvme_ctrlr_depopulate_namespaces().

Additionally, add assert to check if reference count is not negative
to find bug in future.
