Merge tag 'fs.idmapped.docs.v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull fs helper kernel-doc updates from Christian Brauner:
 "In the last cycles we forgot to update the kernel-docs in some places
  that were changed during the idmapped mount work. Lukas and Randy took
  the chance to not just fixup those places but also fixup and expand
  kernel-docs for some additional helpers.

  No functional changes"

* tag 'fs.idmapped.docs.v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux:
  fs: update kernel-doc for vfs_rename()
  fs: turn some comments into kernel-doc
  xattr: fix kernel-doc for mnt_userns and vfs xattr helpers
  namei: fix kernel-doc for struct renamedata and more
