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!
