Subject[PATCH 4.18 23/53] selftests: pmtu: properly redirect stderr to /dev/null
Date
4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sabrina Dubroca <sd@queasysnail.net>

[ Upstream commit 0a286afee5a1e8dca86d824209dbd3200294f86f ]

The cleanup function uses "$CMD 2 > /dev/null", which doesn't actually
send stderr to /dev/null, so when the netns doesn't exist, the error
message is shown. Use "2> /dev/null" instead, so that those messages
disappear, as was intended.

Fixes: d1f1b9cbf34c ("selftests: net: Introduce first PMTU test")
