Hi Linus,
Some fixes and followup features/changes that should go in, in this
merge window. This pull request contains:
- Two fixes for lightnvm from Javier, fixing problems in the new code
merge previously in this merge window.
- A fix from Jan for the backing device changes, fixing an issue in NFS
that causes a failure to mount on certain setups.
- A change from Christoph, cleaning up the blk-mq init and exit request
paths.
- Remove elevator_change(), which is now unused. From Bart.
- A fix for queue operation invocation on a dead queue, from Bart.
- A series fixing up mtip32xx for blk-mq scheduling, removing a bandaid
we previously had in place for this. From me.
- A regression fix for this series, fixing a case where we wait on
workqueue flushing from an invalid (non-blocking) context. From me.
- A fix/optimization from Ming, ensuring that we don't both quiesce and
freeze a queue at the same time.
- A fix from Peter on lock ordering for CPU hotplug. Not a real problem
right now, but will be once the CPU hotplug rework goes in.
- A series from Omar, cleaning up out blk-mq debugfs support, and adding
support for exporting info from schedulers in debugfs as well. This is
really useful in debugging stalls or livelocks. From Omar.
Please pull this for 4.12-rc, thanks!
