Sashiko reported a deadlock during mount, and a use-after-free when an
L3 domain is removed during CPU offline. Reinette found a memory leak
in the mount error path while refactoring code for a solution to the
mount hang. Sashiko found the unmount issue in review of v1 of this
series.

First version of series posted here:

Numerous changes based on comments to v1.

Patch 1 just reorders some code so that fixes can be applied without
adding additional forward declaration of functions.

Patch 2 fixes the memory leak found by Reinette

Patch 3 fixes use-after-free during unmount

Patch 4 fixes the mount deadlock

Patch 5 fixes issues with CPU offline

N.B. Reinette did all the work for patches 4 & 5, so I listed her
as author an me as Co-developer. Those patches need her sign-off.

Reinette Chatre (2):
  fs/resctrl: Fix deadlock for errors during mount
  fs/resctrl: Fix issues with worker threads when CPUs are taken offline

Tony Luck (3):

    fixes
