Kan Liang f38b0dbb49 perf/x86/intel: Introduce PERF_RECORD_LOST_SAMPLES ... After enlarging the PEBS interrupt threshold, there may be some mixed up PEBS samples which are discarded by the kernel. This patch makes the kernel emit a PERF_RECORD_LOST_SAMPLES record with the number of possible discarded records when it is impossible to demux the samples. It makes sure the user is not left in the dark about such discards.
