Namhyung Kim 00f8c6dc82 perf/core: Add a new read format to get a number of lost samples ... [ Upstream commit 119a784c81 ] Sometimes we want to know an accurate number of samples even if it's lost. Currenlty PERF_RECORD_LOST is generated for a ring-buffer which might be shared with other events. So it's hard to know per-event lost count. Add event->lost_samples field and PERF_FORMAT_LOST to retrieve it from userspace.
