[GIT PULL 00/22] perf tools: filtering events using eBPF programs

[Wang Nan]

Hi Arnaldo,

   Have we made any progress on this patch set?

   I have finished my vacation. In this new pull request, I rebase BPF patches
onto the newest perf/core, and fix a document problem in Makefile.perf.

The following changes since commit ae938802443732e77d01f8d5b52b900b9327ff30:

  perf python: Support the PERF_RECORD_SWITCH event (2015-10-07 19:41:50 -0300)

are available in the git repository at:

  perf test: Test BPF prologue (2015-10-08 07:23:33 +0000)

----------------------------------------------------------------
EBPF support for perf

 - Rebase to newest perf/core
