allow link_path_walk() to take ERR_PTR() There is a check for IS_ERR(name) immediately upstream of each call of link_path_walk(name, nd), with positives treated as if link_path_walk() failed with PTR_ERR(name). Taking that check into link_path_walk() itself simplifies things nicely. Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
