Hi Linus,
Followup fixes for this merge window. This pull request contains:
- Series from Ming, fixing corner cases in our CPU <-> queue mapping.
This triggered repeated warnings on especially s390, but I also hit it
in cpu hot plug/unplug testing while doing IO on NVMe on x86-64.
- Another fix from Ming, ensuring that we always order budget and driver
tag identically, avoiding a deadlock on QD=1 devices.
- Loop locking regression fix from this merge window, from Omar.
- Another loop locking fix, this time missing an unlock, from Tetsuo
Handa.
- Fix for racing IO submission with device removal from Bart.
- sr reference fix from me, fixing a case where disk change or getevents
can race with device removal.
- Set of nvme fixes by way of Keith, from various contributors.
Please pull!
