#     Merge tag 'vfs.misc.fixes.v6.3-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping
#     
#     Pull vfs fix from Christian Brauner:
#      "When a mount or mount tree is made shared the vfs allocates new peer
#       group ids for all mounts that have no peer group id set. Only mounts
#       that aren't marked with MNT_SHARED are relevant here as MNT_SHARED
#       indicates that the mount has fully transitioned to a shared mount. The
#       peer group id handling is done with namespace lock held.
#     
#       On failure, the peer group id settings of mounts for which a new peer
#       group id was allocated need to be reverted and the allocated peer
#       group id freed. The cleanup_group_ids() helper can identify the mounts
#       to cleanup by checking whether a given mount has a peer group id set
#       but isn't marked MNT_SHARED. The deallocation always needs to happen
#       with namespace lock held to protect against concurrent modifications
#       of the propagation settings.
#     
#       This fixes the one place where the namespace lock was dropped before
#       calling cleanup_group_ids()"
