From 353ab6e97b8f209dbecc9f650f1f84e3da2a7bb1 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sun, 26 Mar 2006 01:37:12 -0800 Subject: [PATCH] [PATCH] sem2mutex: fs/ Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.
