From 14cc3e2b633bb64063698980974df4535368e98f Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sun, 26 Mar 2006 01:37:14 -0800 Subject: [PATCH] sem2mutex: misc static one-file mutexes Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.
