Subject: [PATCH 04/57] perf test: Report failure for mmap events
Date: Mon, 21 Oct 2019 10:37:41 -0300 [thread overview]
Message-ID: <20191021133834.25998-5-acme@kernel.org> (raw)
In-Reply-To: <20191021133834.25998-1-acme@kernel.org>
From: Leo Yan <leo.yan@linaro.org>
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.
Fixes: d723a55096b8 ("perf test: Add test case for checking number of EXIT events")
