If the clear_ids attribute is set to true, the EUI/GUID/UUID is cleared
for the passthru target.  By default, loop targets will set clear_ids to
true.

This resolves an issue where a connect to a passthru target fails when
using a trtype of 'loop' because EUI/GUID/UUID is not unique.

We encountered a problem that the disconnect command hangs.
After analyzing the log and stack, we found that the triggering
process is as follows:

This problem was not found in older kernels because we will flush

queue stoppage and inflight requests cancellation is fully fenced from
io_work and thus failing a request from this context. Hence we don't
need to try to guess from the socket retcode if this failure is because
the queue is about to be torn down or not.

We are perfectly safe to just fail it, the request will not be cancelled
later on.

Data digest calculation iterates over command mapped iovec. However
since commit bac04454 we unmap the iovec before we handle the data
digest, and since commit 69b85e1f we clear nr_mapped when we unmap
the iov.

Instead of open-coding the command iov traversal, simply call
crypto_ahash_digest with the command sg that is already allocated (we
already do that for the send path). Rename nvmet_tcp_send_ddgst to
nvmet_tcp_calc_ddgst and call it from send and recv paths.

If rq_qos_throttle() ends up blocking, then we will have invalidated and
flushed our current plug. Since blk_mq_get_cached_request() hasn't
popped the cached request off the plug list just yet, we end holding a
pointer to a request that is no longer valid. This insta-crashes with
rq->mq_hctx being NULL in the validity checks just after.

avoid using a potentially stale request.

The block debugfs files are created in blk_register_queue, which is
called by add_disk and use a naming scheme based on the disk_name.
After del_gendisk returns that name can be reused and thus we must not
leave these debugfs files around, otherwise the kernel is unhappy
and spews messages like:

	Directory XXXXX with parent 'block' already present!

and the newly created devices will not have working debugfs files.

Move the unregistration to blk_unregister_queue instead (which matches
the sysfs unregistration) to make sure the debugfs life time rules match
those of the disk name.

As part of the move also make sure the whole debugfs unregistration is
inside a single debugfs_mutex critical section.

Note that this breaks blktests block/002, which checks that the debugfs
directory has not been removed while blktests is running, but that
particular check should simply be removed from the test case.

register debugfs files on demans, which can race with creating and

q->debugfs_dir or the directories hanging off it.

To make the teardown code a little simpler declare all debugfs dentry

Move the blk_qos_exit call as well, as it just depends on the elevator
