There are several test cases in the bpf directory are still using exit 0 when they need to be skipped. Use kselftest framework skip code instead so it can help us to distinguish the return status.
Criterion to filter out what should be fixed in bpf 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.

This bit has been fixed a couple days ago by a similar change:
