From cd19a035f3b63fee6dcbdb5371c4b22276f7dc8c Mon Sep 17 00:00:00 2001 From: Tom Zanussi Date: Thu, 1 Apr 2010 23:59:20 -0500 Subject: perf: Convert perf event types into event type events Bypasses the event type perf header code and replaces it with a synthesized event and processing function that accomplishes the same thing, used when reading/writing perf data to/from a pipe.
