Merge tag 'for-7.2-rc6-fixup-worker-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull Btrfs Fixes 2: Electric Boogaloo from David Sterba:
 "This brings back the fixup worker infrastructure.

  It's a mechanism to detect pages/folios that are marked dirty without
  filesystem knowledge and require COW fixup. The consequence of not
  doing so is silent data loss.

  The first patch covers the scenarios in detail, also reflecting folio
  API port and subpage block size support added in recent years. The
  original fixup worker was only for pages.

  The patch is relatively big, half of the code is debugging and support
  code, the rest is the core design around the detection and fix.

  The second patch handles an unlikely case when there's work left
  during unmount"
