Subject: [PATCH] perf_counter: Fix throttle/unthrottle event logging
Date: Wed, 22 Jul 2009 23:05:46 +1000 [thread overview]
Message-ID: <20090722130546.GE9029@kryten> (raw)
Right now we only print PERF_EVENT_THROTTLE + 1 (ie PERF_EVENT_UNTHROTTLE).
Fix this to print both a throttle and unthrottle event.
