Hi Linus,
A round of fixes/updates for the current series. This looks a little
bigger than it is, but that's mainly because we pushed the lightnvm
enabled null_blk change out of the merge window so it could be updated a
bit. The rest of the volume is also mostly lightnvm. In particular:
- Lightnvm. Various fixes, additions, updates from Matias and Javier, as
well as from Wenwei Tao.
- NVMe:
- Fix for potential arithmetic overflow from Keith.
- Also from Keith, ensure that we reap pending completions from
a completion queue before deleting it. Fixes kernel crashes
when resetting a device with IO pending.
- Various little lightnvm related tweaks from Matias.
- Fixup flushes to go through the IO scheduler, for the cases where a
flush is not required. Fixes a case in CFQ where we would be idling
and not see this request, hence not break the idling. From Jan Kara.
- Use list_{first,prev,next} in elevator.c for cleaner code. From Gelian
Tang.
- Fix for a warning trigger on btrfs and raid on single queue blk-mq
devices, where we would flush plug callbacks with preemption disabled.
From me.
- A mac partition validation fix from Kees Cook.
- Two merge fixes from Ming, marked stable. A third part is adding a new
warning so we'll notice this quicker in the future, if we screw up the
accounting.
- Cleanup of thread name/creation in mtip32xx from Rasmus Villemoes.
Please pull the turkey fixes!
