Subject: [LTP] [PATCH 1/3] cgroup/memcg_regression_test: clear dmesg before test
Date: Mon, 19 Sep 2011 09:49:40 +0200	[thread overview]
Message-ID: <4E76F414.3050200@redhat.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 293 bytes --]


dmesg can rotate and number of found bugs can actually go down,
so clear the buffer before test to avoid this.
