[RFC 0/5] ftrace perf: Fixes and speedup

From: Jiri Olsa
Date: Wed Mar 09 2016 - 15:46:59 EST

sending some small perf related fixes plus one change
to speedup ftrace:function perf registration. I'm still
testing this, but any feedback would be great.

Also available in here:

Jiri Olsa (5):
ftrace perf: Check sample types only for sampling events
ftrace perf: Move exclude_kernel tracepoint check to init event
ftrace perf: Use ftrace_ops::private to store event pointer
ftrace: Make ftrace_hash_rec_enable return update bool
ftrace: Update dynamic ftrace calls only if necessary
