The netdev CI runs in a VM and captures serial, so stdout and stderr get combined. Because there's a missing new line in stderr the test ends up corrupting KTAP:
# Successok 1 selftests: net: reuseaddr_conflict
which should have been:
# Success ok 1 selftests: net: reuseaddr_conflict
Fixes: 422d8dc6fd3a ("selftest: add a reuseaddr test") Signed-off-by: Jakub Kicinski kuba@kernel.org --- Low risk and seems worth backporting to stable, hence the fixes tag.
