Subject: [PATCH bpf-next v3 04/15] selftests/xsk: print correct error codes when exiting
From: Magnus Karlsson <magnus.karlsson@...el.com>
Print the correct error codes when exiting the test suite due to some
terminal error. Some of these had a switched sign and some of them
printed zero instead of errno.
Fixes: facb7cb2e909 ("selftests/bpf: Xsk selftests - SKB POLL, NOPOLL")
