NOTE: This patch series is based on: https://lore.kernel.org/fstests/20250626002735.22827-1-catherine.hoang@xxxxxxxxxx/T/#t Changes in v3: - (2/13) use dumpe2fs to figure out if FS is bigalloc - (9/13) generic/1230: Detect device speeds for more accurate testing. ALso speeds up the test - fio tests - switch to write followed by verify approach to avoid false failures due to fio verify reads splitting and racing with atomic writes. Discussion thread: https://lore.kernel.org/fstests/0430bd73-e6c2-4ce9-af24-67b1e1fa9b5b@xxxxxxxxxx/ Changes in v2 [1]: - (1/13) new patch with _min and _max helpers - (2/13) remove setup_fs_options and add fsx specifc helper - (4/13) skip atomic write instead of falling back to normal write (fsx) - (4/13) make atomic write default on instead of default off (fsx) - (5,6/13) refactor and cleanup fio tests - (7/13) refactored common code - (8/13) dont ignore mmap writes for fsx with atomic writes - (9/13) use od instead of xxd. handle cleanup of bg threads in _cleanup() - (10-13/13) minor refactors - change all tests use _fail for better consistency - use higher tests numbers for easier merging [1] https://lore.kernel.org/fstests/cover.1750924903.git.ojaswin@xxxxxxxxxxxxx/ * Original cover [2] * These are the tests we were using to verify that filesystems are not tearing multi fs block atomic writes. Infact some of the tests like generic/772 (now: g/1230) actually helped us catch and fix issues in ext4's early implementations of multi fs block atomic writes and hence we feel these tests are useful to have in xfstests. We have tested these with scsi debug as well as a real nvme device supporting multi fs block atomic writes. Thoughts and suggestions are welcome!
