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.
Changes in v2:
- Update the comment of patch [2/5] for explaining more
detail of the backgroud.
