See [1] for full explanation. Only patch 6 has changed vs v2. The rest are the same and already carry reviewed/acked-bys. So I'm hoping I can get the final patch reviewed and this series is hopefully then good enough to merge? Changes Since v2 [2] -------------------- - Patch 6: Change approach to cleaning up child processes; Use "parent death signal", as suggested by David. - Added Reviewed-by/Acked-by tags: thanks to David, Mark and Peter! Changes Since v1 [1] -------------------- - Patch 1: Explicitly set line buffer mode in ksft_print_header() - Dropped v1 patch 2 (set execute permissions): Andrew has taken this into his branch separately. - Patch 2: Don't compile `soft-dirty` suite for arm64 instead of skipping it at runtime. - Patch 2: Declare fewer tests and skip all of test_softdirty() if soft-dirty is not supported, rather than conditionally marking each check as skipped. - Added Reviewed-by tags: thanks DavidH! - Patch 8: Clarified commit message.
