TOMOYO: Extract bitfield
Since list elements are rounded up to kmalloc() size rather than sizeof(int), saving one byte by using bitfields is no longer helpful. Signed-off-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Acked-by: Serge Hallyn <serue@us.ibm.com> Signed-off-by: James Morris <jmorris@namei.org>
