From f71c49e5e985897850406a152ab99001cfb86f2a Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 2 Dec 2011 13:53:04 -0200 Subject: [PATCH] perf test: Soft errors shouldn't stop the "Validate PERF_RECORD_" test For errors that don't preclude checking for further errors, aka "soft" errors, just continue testing for other errors. Better coverage in verbose mode.
