    Subject[GIT PULL 00/29] perf tools: filtering events using eBPF programs
    Date
    Hi Arnaldo,

    This is the first time I use my new kernel.org account to generate pull
    request for you. I hope it work.

    The following changes since commit acc60583a43fe93ff42d707a39d478c7dbe24028:

    perf tools: Fix Intel PT timestamp handling (2015-08-20 16:45:01 -0300)

    are available in the git repository at:

    git://git.kernel.org/pub/scm/linux/kernel/git/pi3orama/linux tags/perf-ebpf-for-acme-20150821

    for you to fetch changes up to 15756861299809103c00d9342352eb22bb84f20f:

    perf tools: Support attach BPF program on uprobe events (2015-08-21 03:57:12 +0000)

    ----------------------------------------------------------------
    perf bpf improvements:

    - Improve 'perf test BPF'

    Don't use the hacking way in previous series that make perf act test
    target and run 'perf record' using system().

    In this series, perf test BPF open the evlist and evsel, attach then
    record, analysis result in its own context.

    - Improve error reporting

    Use strerror style error reporting. Only output debug information
    in bpf-loader.c.
