[PATCHv3 00/12] nvme and blk-mq hot plug fixes

[Keith Busch]

Changes since version 2:

Attribute patch from Jens. There was no change log with the diff, so I
just made one up. You're a better wordsmith so I won't be feel bad
if you modify it.

Added new cmd_flag for REQ_NO_TIMEOUT, as opposed to using a magic value
for "rq->timeout" from v2.

Fixed the irq save/restore locking when checking for stopped queue in
req_completion requeue.

I noticed the timeout handling was accessing unlocked queues and dev
list nodes, so I added one last patch for that.

I split the admin queue reference count into its own patch. The previous
patch was changing too many logically separate things.

I put a "FIXME" in the timeout handling on a failed shutdown to speed
things up. I know how to fix this but it's a more radical change that
can go in a different series; making hot-plug and resets work safely is
a higher priority.
