fs/namespace.c: path_is_under can be boolean
This patch makes path_is_under return bool to improve readability due to this particular function only using either one or zero as its return value. No functional change. Signed-off-by: Yaowei Bai <baiyaowei@cmss.chinamobile.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
