Subject: [GIT PULL 00/27] perf tools: filtering events using eBPF programs
Hi Arnaldo,
This is patches needs to be reviewed after Ingo's pull. In this series,
I made following improvements:
1. Remove all pr_err and introduce bpf__strerror_{prepare_load,probe,load}.
All callers are switched to strerror style;
2. Avoid the global 'struct perf_probe_event' array used by perf__probe(). This
is done by moving config_bpf_program() to bpf__probe().
The following changes since commit 64d3e6a927b9fef30efafc0aacab563a3065db24:
perf tools: Unset perf_event_attr::freq when period term is set (2015-08-08 14:32:00 -0300)
are available in the git repository at:
