[PATCH 0/9] blk-mq-debugfs: scheduler support and cleanups

[Omar Sandoval <osandov@osandov.com>]

From: Omar Sandoval <osandov@fb.com>

Hi,

This series makes more enhancements to blk-mq-debugfs.

- Patch 1 is a subjective change.
- Patches 2 and 3 are cleanups.
- Patch 4 is Bart's patch from a couple of weeks ago, necessitated by
  patch 6.
- Patch 5 is another cleanup.
- Patch 6 reworks the lifetimes of the debugfs attributes to be tied to
  the structure lifetimes themselves rather being duct taped on to
  sysfs. This is what I should have done in the first place, and would
  have also been a way to fix the same thing we fixed in e869b5462f83
  ("blk-mq: Unregister debugfs attributes earlier"), but I didn't think
  of doing it this way until I started adding scheduler support.
- Patch 7 allows schedulers to register debugfs attributes, implemented
  in patches 8 and 9 for kyber and mq-deadline, respectively.

Please take a look and give it a spin.

Thanks!
