Commit 364a453a authored May 13, 2022 by Linus Torvalds

Merge tag 'mm-hotfixes-stable-2022-05-11' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull misc fixes from Andrew Morton:
 "Seven MM fixes, three of which address issues added in the most recent
  merge window, four of which are cc:stable.

  Three non-MM fixes, none very serious"

[ And yes, that's a real pull request from Andrew, not me creating a
  branch from emailed patches. Woo-hoo! ]
