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

hi,
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:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  ftrace/fixes

thanks,
jirka

      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
