57dd0d5085 bdev/raid: Get struct raid_bdev from struct spdk_bdev_io in IO submission
During IO submission, raid_bdev can be get by bdev_io->bdev->ctxt.
Hence holding raid_bdev in raid_bdev_io_channel is duplicated.

a9b9f0952d nvmf/rdma: Don't trigger error recovery on IBV_EVENT_SQ_DRAINED
IBV_EVENT_SQ_DRAINED can occur during both error recovery and
normal operation. We don't want to spend time sending a message
to the correct qpair thread and then attempting to abort
all I/O in the case where this wasn't triggered by an error.

The case where this occurs during an error is very rare and
only in response to a user forcing the state to err from the
sqd state. For now, don't handle that case at all. Handle that
corner case in a later patch.

27635c770f bdev: track io_stats from deleted channels
Currently, the bdev layer iterates over all of the
existing channels of a bdev to collect I/O
statistics.  But this ignores statistics for
channels that are deleted.

Fix that by keeping an io_stat structure in the
bdev which accumulates statistics for deleted
channels.  Use the bdev mutex to protect these
accumulations.

4c4cba9a95 nvmf: simplify the qpair_mask handling.
We should not use mutex, but use the spdk_send_msg policy,
then we can let only one thread to handle that and
eliminates the segement fault issue.

Now in the code, the qpair_mask is handled by the same
thread, e.g., the thread which owns the admin qpair of
the ctrlr.

f2b22d68d6 subsystem: defer channel iter until pg functions return
The poll group pause, resume, remove, and add functions are only called
from the subsystem_state_change_on_pg function. Previously, they would
return immediately and the state change would move on to the next
channel. However, some of these functions (specifically remove) kick off
asynchronous APIs and we should not iterate past them until those
asynchronous operations complete.

b326e51219 bdev/virtio_blk: defer bdev destruct completion
Even after the bdev is removed, the underlying virtio
device may be still alive for some time. The user may
then try to recreate the virtio bdev and could technically
initialize a second simultaneous connection to a vhost
target. It does not cause any technical problems, but the
target may reject such connection if it reached a connection
cap or doesn't support more than one connection per target
(like SPDK vhost does as of today).

Since the fix is straightforward, here it is.

Note:
Virtio SCSI is already safe, because it uses a separate
completion callback to indicate virtio device destruction.

a1ec258ac7 Clean up some incorrect Copyright statements
Daisuke Aoyama originally contributed to istgt, the
iSCSI target in FreeBSD. The SPDK iSCSI code is
originally derived from that. Due to copy and paste,
some incorrect copyright attributions have been added
to other files that do  not derive from istgt, so
this patch removes those.

It is doubtful, at this point, that there is any code
whatsoever that remains from the original istgt, but
we can revisit that at a later time.

c60ae3c356 raid: get buffer on reads before sending child ios
For front-ends like iSCSI (and NVMe-oF in the future)
which want the backend to specify the data buffer, the
RAID module doesn't copy the pointer to the allocated
buffer from the child IO back to the parent IO.  It
really can't copy the pointer - the child IO owns it
and will free it.

So the RAID module needs to allocate the buffer first
and then pass it down.

For example, when freeing a qpair, one needs to free the AER sent from

1. According to the spec, this will trigger the host to send another AER
2. No Asynchronous Events have occured, so we should not complete the

The DPDK config file is not located in this directory
yet to preserve some of the backward compability.
