dcache: d_splice_alias should ignore DCACHE_DISCONNECTED
Any IS_ROOT() alias should be safe to use; there's nothing special about DCACHE_DISCONNECTED dentries. 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.
