Subject: [PATCH 3/3] selftests/livepatch: filter 'taints' from dmesg comparison
Date: Wed, 10 Jun 2020 13:21:01 -0400	[thread overview]
Message-ID: <20200610172101.21910-4-joe.lawrence@redhat.com> (raw)
In-Reply-To: <20200610172101.21910-1-joe.lawrence@redhat.com>

The livepatch selftests currently filter out "tainting kernel with
TAINT_LIVEPATCH" messages which may be logged when loading livepatch
modules.

Further filter the log to drop "loading out-of-tree module taints
kernel" in the rare case the klp_test modules have been built
out-of-tree.
