Subject: [PATCHSET 00/12] perf tools: Apply percent-limit to callchains

Hello,

This patchset tries to implement percent limit to callchains which was
requested by Andi Kleen.  For some reason, limiting callchains by
(overhead) percentage didn't work well.  This patch fixes it and make
--percent-limit also works for callchains as well as hist entries.

This is available on 'perf/callchain-limit-v1' branch in my tree:

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Any comments are welcome,

Thanks,
Namhyung
