Merge tag 'fs.mount_setattr.v5.17-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull mount_setattr test/doc fixes from Christian Brauner:
 "This contains a fix for one of the selftests for the mount_setattr
  syscall to create idmapped mounts, an entry for idmapped mounts for
  maintainers, and missing kernel documentation for the helper we split
  out some time ago to get and yield write access to a mount when
  changing mount properties"

* tag 'fs.mount_setattr.v5.17-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux:
  fs: add kernel doc for mnt_{hold,unhold}_writers()
  MAINTAINERS: add entry for idmapped mounts
  tests: fix idmapped mount_setattr test
