This patch set is based on perf/core. Compare with v1: - Patch 1/13 and 9/13: make code compat based on Arnaldo's suggestion; - Patch 4/13: fix a bug which incorrectly use list_is_singular() test whether a list entry is deleted from a list; - Patch 13/13: change another test case.
This patch set improves perf's BPF support: - Support filling BPF array with values Users are allowed to pass something to BPF program through command line without changing the program itself. - Support filling BPF event array with events BPF program can read PMU counters through BPF's perf_event_read() helper. - Support bpf_output_event() helper BPF program can issue perf event to perf.data. In most of the patches I list commands for testing them, both normal case and error case.
