[PATCH 0/3] perf: Remove orphaned children events

[Jiri Olsa]

hi,
adding a support to remove orphaned children events, so they do not
eat resources once parent event is gone as discussed here:
  lkml.kernel.org/r/1405079782-8139-3-git-send-email-jolsa@xxxxxxxxxx
and here:
  http://marc.info/?l=linux-kernel&m=140568679618148&w=2

Also reachable in here:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  perf/core_orphans_removal

thanks,
jirka
