#     Merge tag 'fs.idmapped.mount_setattr.v5.13-rc3' of gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux
#     
#     Pull mount_setattr fix from Christian Brauner:
#      "This makes an underlying idmapping assumption more explicit.
#     
#       We currently don't have any filesystems that support idmapped mounts
#       which are mountable inside a user namespace, i.e. where s_user_ns !=
#       init_user_ns. That was a deliberate decision for now as userns root
#       can just mount the filesystem themselves.
#     
#       Express this restriction explicitly and enforce it until there's a
#       real use-case for this. This way we can notice it and will have a
#       chance to adapt and audit our translation helpers and fstests
#       appropriately if we need to support such filesystems"
