Merge branch 'bpf-perf'
Alexei Starovoitov says: ==================== bpf_perf_event_output helper Over the last year there were multiple attempts to let eBPF programs output data into perf events by He Kuang and Wangnan. The last one was: https://lkml.org/lkml/2015/7/20/736 It was almost perfect with exception that all bpf programs would sent data into one global perf_event. This patch set takes different approach by letting user space open independent PERF_COUNT_SW_BPF_OUTPUT events, so that program output won't collide. Wangnan is working on corresponding perf patches. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
