[GIT PULL 00/31] perf tools: filtering events using eBPF programs

From: Wang Nan
Date: Sat Aug 29 2015 - 00:22:45 EST

Hi Arnaldo and Ingo,

Several small proglems are fixed based on yesterday's pull request. Please
see below. Since patch order is changed (original 20/32 and 32/32 are
dropped), I decide to send all of them again. Sorry for the noisy.

In addition: I collect a cross-compiling fix I posted yesterday into this
cset (the last one).

The following changes since commit 2c07144dfce366e21465cc7b0ada9f0b6dc7b7ed:

perf evlist: Add backpointer for perf_env to evlist (2015-08-28 14:54:14 -0300)

tools lib traceevent: Support function __get_dynamic_array_len (2015-08-29 02:57:40 +0000)

----------------------------------------------------------------
perf BPF related improvements and bugfix:

- Rebase to Arnaldo's newest perf/core.

- Fix a missing include in builtin-trace.c.

- Drop patch 'perf tools: Fix probe-event.h include' since
the problem has been fixed by commit 5a023b57.

- Fix a cross compiling error (introduced by inter pt).

- Drop patch 'bpf: Introduce function for outputing data to
perf event' because we want to do better.
