Subject: [PATCH 0/5] Add glob pattern matching support on trigger and kprobe-event
Date: Thu, 16 May 2013 20:48:40 +0900	[thread overview]

Hi,

Here is a series of ftrace/perf updates to support multiple
event select operation by glob-based wild cards.
I've ported strglobmatch from perf-tools (with recursive call
limitation) for this use. It is easier to use (just replacing
strcmp) but slower than current parser-based matching.
I don't care about the speed of matching because the all of
the matching which I've introduced in this series are done
on slow-path.
