From 5f3ea37c7716db4e894a480e0c18b24399595b6b Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 30 Oct 2008 08:34:33 +0100 Subject: blktrace: port to tracepoints This was a forward port of work done by Mathieu Desnoyers, I changed it to encode the 'what' parameter on the tracepoint name, so that one can register interest in specific events and not on classes of events to then check the 'what' parameter.
