From f737d95ddfea4df68a36ffc9231db4bf34b06d13 Mon Sep 17 00:00:00 2001 From: Tetsuo Handa Date: Sun, 3 Jan 2010 21:16:32 +0900 Subject: 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.
