selftests: pmtu: properly redirect stderr to /dev/null
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") Signed-off-by: Sabrina Dubroca <sd@queasysnail.net> Acked-by: Stefano Brivio <sbrivio@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
