Subject: [PATCH v2 0/5] Add glob pattern matching support on trigger and
 kprobe-event

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.

      [BUGFIX] tracing: Returns -EBUSY when event_enable_func fails to get module
      perf: Swap the parameters of strglobmatch
      lib/string: Add a generic wildcard string matching function
      tracing/kprobes: Allow user to delete kprobe events by wild cards
      tracing: Support enable/disable multiple events trigger by wild cards
