From 6260618e09d375ee6aa19be16813dac40cc47513 Mon Sep 17 00:00:00 2001 From: Po-Hsu Lin Date: Thu, 2 Sep 2021 14:56:08 -0700 Subject: [PATCH] selftests/vm: use kselftest skip code for skipped tests There are several test cases in the vm directory are still using exit 0 when they need to be skipped. Use the kselftest framework to skip code instead so it can help us to distinguish the return status. Criterion to filter out what should be fixed in vm directory: grep -r "exit 0" -B1 | grep -i skip This change might cause some false-positives if people are running these test scripts directly and only checking their return codes, which will change from 0 to 4. However I think the impact should be small as most of our scripts here are already using this skip code. And there will be no such issue if running them with the kselftest framework.
