From fec70569a3e15aea34a4b22500ff2ba3830d789f Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Tue, 17 Jul 2012 10:45:59 -0400 Subject: [PATCH 275/290] cpu/rt: Fix cpu_hotplug variable initialization 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.
