Hi,
This series improves the ublk selftests infrastructure with better
organization and parallel test execution support.
Key improvements:
1. Infrastructure enhancements:
- Add helper functions for device cleanup and parallel execution
- Implement group-based test targets for running test subsets
- Track created devices for proper per-test cleanup
- Increase timeouts to accommodate parallel test execution
- Test time can be reduced to 1/3 with parallel execution by passing JOBS=8
2. Test organization:
- Reorganize tests into logical groups (integrity, recover)
- Refactor large tests into modular functions for maintainability
3. I/O ordering verification:
- Remove test_generic_01.sh prone to false positives from block layer
reordering
- Improve test_generic_02.sh with bpftrace-based verification
- Use block_io_start/block_rq_complete tracepoints for accurate tracking
These changes make the test suite more maintainable, easier to run in parallel,
and more reliable in detecting actual ublk driver issues vs. false positives.
