Subject: [PATCH 1/3] tracing: Make TRACE_ITER_STOP_ON_FREE stop the correct buffer
Date: Fri, 2 Aug 2013 18:36:15 -0700 [thread overview]
Message-ID: <1375493777-17261-1-git-send-email-azl@google.com> (raw)
Releasing the free_buffer file in an instance causes the global buffer
to be stopped when TRACE_ITER_STOP_ON_FREE is enabled. Operate on the
correct buffer.
