Subject: [GIT PULL] overlayfs fixes for 5.11-rc7

Hi Linus,

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git tags/ovl-fixes-5.11-rc7

- Fix capability conversion and minor overlayfs bugs that are related to
  the unprivileged overlay mounts introduced in this cycle.

- Fix two recent (v5.10) and one old (v4.10) bug.

- Clean up security xattr copy-up (related to a SELinux regression).

Thanks,
Miklos
