Subject: selftests/bpf: Use kselftest skip code for skipped tests
Patch-mainline: v5.16-rc1
Git-commit: d4b6f87e8d3929d3d1594fca0256299113301fd7
References: jsc#PED-1377
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.
