[PATCH 14/16] perf record: Reset event name when falling back to cpu-clock
From: Arnaldo Carvalho de Melo
Date: Thu May 10 2012 - 13:22:47 EST
From: David Ahern <dsahern@xxxxxxxxx>
perf-record defaults to the H/W cycles event and if it is not supported
falls back to cpu-clock. Reset the event name as well.
