Note that this is in fact useful for filesystems such as btrfs which can legimately encounter a directory with a preexisting IS_ROOT alias on a lookup that crosses into a subvolume. (Those aliases are currently marked DCACHE_DISCONNECTED--but not really for any good reason, and we'll change that soon.) Signed-off-by: J.
