From ef2bf6d043ac9bd4a6f38d862af407154a4754d9 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Sat, 29 Jan 2011 09:04:40 -0200 Subject: [PATCH] perf events: Account PERF_RECORD_LOST events in event__process Right now this function is only used by perf top, that uses PROT_READ only, i.e. overwrite mode, so no PERF_RECORD_LOST events are generated, but don't forget those events. The patch that moved this out of perf top was made so that this routine could be used by 'perf probe' in the uprobes patchset, so perhaps there they need to check for LOST events and warn the user, as will be done in the following patches that will switch 'perf top' to non overwrite mode (mmap with PROT_READ|PROT_WRITE).
