From mboxrd@z Thu Jan 1 00:00:00 1970 From: Steven Rostedt Subject: [PATCH RT 09/12] cpu/rt: Fix cpu_hotplug variable initialization Date: Tue, 17 Jul 2012 11:31:24 -0400 Message-ID: <20120717153244.496531903@goodmis.org> References: <20120717153115.606116459@goodmis.org> Cc: Thomas Gleixner , Carsten Emde , John Kacur To: linux-kernel@vger.kernel.org, linux-rt-users Return-path: Content-Disposition: inline; filename=0009-cpu-rt-Fix-cpu_hotplug-variable-initialization.patch Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-rt-users.vger.kernel.org From: Steven Rostedt The commit "cpu/rt: Rework cpu down for PREEMPT_RT" changed the double meaning of the cpu_hotplug.lock, where it was a spinlock for RT and a mutex for non-RT, to just a mutex for both. But the initialization of the variable was not updated to reflect this change.
