From 24c0a10be37d0f0f8634350e1adb5c5ae141a720 Mon Sep 17 00:00:00 2001 From: Leo Yan Date: Fri, 11 Oct 2019 17:19:41 +0800 Subject: [PATCH] perf test: Report failure for mmap events [ Upstream commit 6add129c5d9210ada25217abc130df0b7096ee02 ] When fail to mmap events in task exit case, it misses to set 'err' to -1; thus the testing will not report failure for it. This patch sets 'err' to -1 when fails to mmap events, thus Perf tool can report correct result.
