From e3968fc0f3db58e4c448ec20f66ce6da49d9bc5f Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 20 Mar 2006 22:34:25 -0800 Subject: [SUNGEM]: sem2mutex Semaphore to mutexes conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well. Signed-off-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: David S.
