From e2df9e0905136eebeca66eb9a994ca48d0fa7990 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 14 Apr 2008 08:50:02 +0200 Subject: [PATCH] revert "sched: fix fair sleepers" revert "sched: fix fair sleepers" (e22ecef1d2658ba54ed7d3fdb5d60829fb434c23), because it is causing audio skipping, see: http://bugzilla.kernel.org/show_bug.cgi?id=10428 the patch is correct and the real cause of the skipping is not understood (tracing makes it go away), but time has run out so we'll revert it and re-try in 2.6.26.
