In the end of the test, there will be an error message induced by the `ip netns del ns1` command in cleanup()
Tests passed: 201 Tests failed: 0 Cannot remove namespace file "/run/netns/ns1": No such file or directory
Redirect the error message to /dev/null to mute it.
Fixes: a0e11da78f48 ("fib_tests: Add tests for metrics on routes")
I don't think this tag is correct. More likely that this is caused by commit b60417a9f2b8 ("selftest: fib_tests: Always cleanup before exit").
You can even reproduce it with '-h':
# ./fib_tests.sh -h usage: fib_tests.sh OPTS [...] Cannot remove namespace file "/var/run/netns/ns1": No such file or directory
Reverting the commit I mentioned makes it go away.
Also, please use "PATCH net" prefix: https://www.kernel.org/doc/html/latest/process/maintainer-netdev.html#tl-dr
