Hello Jens and guys,
This patchset fixes several issues(1, 2, 4) and consolidate & improve the tests in the following ways:
- support shellcheck and fixes all warning
- misc cleanup
- improve cleanup code path(module load/unload, cleanup temp files)
- help to reuse the same test source code and scripts for other projects(liburing[1], blktest, ...)
- add two stress tests for covering IO workloads vs. removing device & killing ublk server, given buffer lifetime is one big thing for ublk-zc
[1] https://github.com/ming1/liburing/commits/ublk-zc
- just need one line change for overriding skip_code, libring uses 77 and kselftests takes 4
