Pull block fixes from Jens Axboe:
"Here's a pull request for 4.11-rc, fixing a set of issues mostly
centered around the new scheduling framework. These have been brewing
for a while, but split up into what we absolutely need in 4.11, and
what we can defer until 4.12. These are well tested, on both single
queue and multiqueue setups, and with and without shared tags. They
fix several hangs that have happened in testing.
This is obviously larger than I would have preferred at this point in
time, but I don't think we can shave much off this and still get the
desired results.
In detail, this pull request contains:
- a set of five fixes for NVMe, mostly from Christoph and one from
Roland.
- a series from Bart, fixing issues with dm-mq and SCSI shared tags
and scheduling. Note that one of those patches commit messages may
read like an optimization, but it is in fact an important fix for
queue restarts in particular.
- a series from Omar, most importantly fixing a hang with multiple
hardware queues when we fail to get a driver tag. Another important
fix in there is for resizing hardware queues, which nbd does when
handling multiple sockets for one connection.
- fixing an imbalance in putting the ctx for hctx request allocations
from Minchan"
