The testings are done this way

1. build zfs modules for Ubuntu 20.04 and 22.04 (~15m)
2. 2x zloop test (~10m) + 2x sanity test (~25m)
3. functional testings in parts 1..5 (each ~1h)
4. cleanup and create summary
   • content of summary depends on the results of the steps

When everything runs fine, the full run should be done in about 2 hours.

The codeql.yml and checkstyle.yml are not part in this circle.
