From 910f5d202ce39cc78de1bbb679285a3167de9fb2 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 23 Mar 2006 03:00:39 -0800 Subject: [PATCH] sem2mutex: sound/oss/ Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.
