Subject: [GIT PULL 00/32] perf tools: filtering events using eBPF programs
Hi Arnaldo,
This time I adjust all Cc and Link field in each patch.
Four new patches (1,2,3,12/32) is newly introduced for fixing a bug
related to '--filter' option. Patch 06/32 is also modified. Please keep
an eye on it.
Since Steven is not very responsive, I still keep patch 31 and 32 in my
tree.
The following changes since commit 327938ee9ea16cc03f02f0e9cc74cdc6ac704cc6:
tools lib traceeveent: Allow for negative numbers in print format (2015-08-27 11:13:53 -0300)

bpf: Introduce function for outputing data to perf event (2015-08-28 06:24:43 +0000)
----------------------------------------------------------------
perf BPF related improvements and bugfix:
- Call bpf__clear() in command 'record, top, stat and trace' to ensure
release BPF related resources.
- Correct --filter option when try to apply filter to BPF object.
