From fbf1396992d57eae7225800226720015469de0fc Mon Sep 17 00:00:00 2001 From: John Kacur Date: Thu, 15 Oct 2009 21:09:32 +0200 Subject: [PATCH] ipc: fix rt/non_rt imbalance commit 1920d618c37ee53bb424a32f26076af2fa5b2a8b in tip. commit 3c96a2 (ipc: Make the ipc code -rt aware) introduced a imbalance of preempt_disable_rt vs. preempt_enable_nort. That results in preempt count leak. Make it symetric.
