[PATCH 00/12] perf top: Rework processing code

[Jiri Olsa]

hi,
David reported issues with perf top loosing side band events
so we moved mmap reading and hists processing into separated
threads.

This patchset also adds dropping sample logic when the processing
falls behind the reader thread. This way we get incomplete but
current data in perf top.

Also available in:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  perf/fixes

thanks,
jirka
