spdk_iscsi_tgt_node_access() (in lib/iscsi/tgt_node.c) regards
empty netmask of IG as ALL (allow all initiator's IP address).
However any user cannot create IG whose netmask is empty by both
JSON-RPC and config file. Instead user can create IG whose
netmask is ALL.
The code to regard empty netmask of IG as ALL never run in production.
Hence delete the code and add UT to confirm the fix.

Finish paths for subsystems, bdevs and copy engine is now
asynchronous.
Each of those three mentioned have to make sure they are
asynchronous as well.
Only bdev that currently has requirement for asynchronous finish
are logical volume.
Thus the change in vbdev_lvol.c making it move to next bdev module
only after all lvol stores were unloaded.
Fio_plugin finish of bdev and copy_engine was removed for now.

at that point it is known that it can be used. Meanwhile removing
was done at start of _vbdev_lvs_remove, to prevent possibility to
access it when waiting for destruct callback to complete.
This made checking if the g_spdk_lvol_pairs list is empty unreliable
to detect if all lvs were destroyed - they could still be being
processed and callback not yet called.
This patch removes lvs from global list only after the callback of
_vbdev_lvs_remove is called.

This also preserves the original bdev_io->status code set by the module,

The vhost connection can be closed
concurrently from 2 places:
* the connection thread itself
* rte_vhost_driver_unregister
The connection thread will terminate
the connection if any recv error
occured. The unregister function
will terminate the connection
together with the thread.
However, there is no sychronization
between those two. The connection
thread runs in the background
without any mutex.
The rte_vhost_driver_unregister
now signals the connection thread
to terminate itself and waits
until it's killed.

This patch also introduces
vq->poller_ctx. It will be later
reused for per-virtqueue task pools
to allow multiple threads using
the same virtqueue.
Since at the time of scanning there
is no I/O traffic, this field is
now being used to keep scan base
pointer. It has to be freed if an
initialization error occurs.

Some of the task struct fields

just once - at the vdev start/stop.
This simplifies the code, the
debugging process and also introduces
additional sanity check preventing
vhost from processing two requests

by a logical CPU core in order to
perform any traffic on them. The
acquire mechanism is thread-safe to
prevent two reactors accessing the
same virtqueue at the same time.
For now a single virtqueue
may be used by only one io_channel.
Support for shared virtqueues will
be implemented in future.
Added new param "Queues" to the

spdk_lvol_destroy() and spdk_lvol_close() behave very similar to

after closing the blob.
The order of calls in spdk_lvol_destroy() case:
- spdk_lvo_destroy() calls spdk_bs_md_close_blob()
- _spdk_lvol_delete_blob_cb is callback from closing the blob,
which calls spdk_bs_md_delete_blob()
- _spdk_lvol_close_blob_cb is callback from deleting the blob
The order of calls in spdk_lvol_close() case:
- spdk_lvo_close() calls spdk_bs_md_close_blob()
- _spdk_lvol_close_blob_cb is callback from closing the blob
Lvol was removed from lvol store lvol list in two cases,
spdk_lvol_destroy() and _spdk_lvol_close_blob_cb().
This caused lvol to be removed twice from the list in
lvol destroy case.
This change makes it so it is more clear, that lvol is removed
from lvol store lvol list in both cases and just once.

Every descriptor may now contain
a separate descriptor table.
This increases the maximum number
of concurrent IO in a virtqueue
from about (vq->size / 3) to
(vq->size * SPDK_VHOST_IOVS_MAX).
Knowing that SPDK_VHOST_IOVS_MAX
is 128, and assuming that vq->size
is 128 (current hardcoded limit
for QEMU), this gives us over 16k
concurrent possible iovectors
on the fly

With this new API, callers can attach one specific ctrlr identified by
the transport ID directly along with optional ctrlr opts. If connecting
to multiple controllers, it is still suggested to use spdk_nvme_probe()
and filter the requested controllers with the probe callback.
Two primary use cases:
1) connecting to the NVMe-oF discovery controller
2) more straightforward way to connect a specific controller (avoiding
the probe callback)
A typical usage of this API with specific ctrlr_opts:
1. struct spdk_nvme_ctrlr_opts user_opts = {}
2. Call spdk_nvme_ctrlr_get_default_ctrlr_opts(&user_opts, sizeof(user_opts))
3. Modify the content of the initialized user_opts with user required value like
user_opts.num_io_queues = 8
4. Call spdk_nvme_connect(&trid, &user_opts, sizeof(user_opts))

With current SPDK_BDEV_LARGE_BUF_MAX_SIZE
set to 65536, we can allocate at most
4095 16-byte SCSI UNMAP block descriptors.
A single descriptor can UNMAP up to 4GB.
That gives us a hard limit of ~16 terabytes
of data that can be unmmapped by a single
request.
The same limit is also enforced by the
SCSI standard, as the entire UNMAP request
length must be smaller than 65536.
