Subject: [PATCH v1 1/2] perf test: Report failure for mmap events
Date: Fri, 11 Oct 2019 17:19:41 +0800
Message-ID: <20191011091942.29841-1-leo.yan@linaro.org> (raw)

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.
