Subject: [PATCH 07/19] tracing: Have tracing_sched_wakeup_trace() use standard unlock_commit
Date: Fri, 02 Nov 2012 14:13:38 -0400 [thread overview]
Message-ID: <20121102181431.031622010@goodmis.org> (raw)

From: Steven Rostedt <srostedt@redhat.com>
The functon tracing_sched_wakeup_trace() does an open coded unlock
commit and save stack. This is what the trace_nowake_buffer_unlock_commit()
is for.
