From 966ee4d6b887c14159043ac80b8c3661d2bbe5e2 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Wed, 22 Jul 2009 23:05:46 +1000 Subject: [PATCH] perf_counter: Fix throttle/unthrottle event logging Right now we only print PERF_EVENT_THROTTLE + 1 (ie PERF_EVENT_UNTHROTTLE). Fix this to print both a throttle and unthrottle event.
