do_lookup() fix do_lookup() has a path leading from LOOKUP_RCU case to non-RCU crossing of mountpoints, which breaks things badly. If we hit need_revalidate: and do nothing in there, we need to come back into LOOKUP_RCU half of things, not to done: in non-RCU one. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
