TOMOYO: Replace rw_semaphore by mutex.
Since readers no longer use down_read(), writers no longer need to use rw_semaphore. Replace individual rw_semaphore by single mutex. 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>
