Subject: [PATCH] selftests: Use kselftest skip code for skipped tests
There are several test cases still using exit 0 when they need to be
skipped. Use kselftest framework skip code instead so it can help us
to distinguish the proper return status.
Criterion to filter out what should be fixed in selftests 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.
