From 380e29a6b71fac7ce7a437ab2f7e305c3de8076f Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Sat, 17 Mar 2018 02:31:38 +0100 Subject: [PATCH] selftests: pmtu: Reverse return codes of functions David suggests it's more intuitive to return non-zero on failures, and zero on success. No need to introduce tail 'return 0' in functions, they will return the exit code of the last command anyway. Suggested-by: David Ahern Signed-off-by: Stefano Brivio Signed-off-by: David S.
