Subject[PATCH] perf test: Add bpf-output event
From 8f71d55dd3e27e6ca2138e3ed6dfeceb1c00a426 Mon Sep 17 00:00:00 2001

Subject: [PATCH] perf test: Add bpf-output event

The kernel has added support for 'PERF_COUNT_SW_BPF_OUTPUT' but that is
missing from the perf tool. Among other things, results in the 'roundtrip
evsel->name check' test case of 'perf test' failing on Powerpc.
