Add tests for btrfs' raid-stripe-tree feature. All of these test work by writing a specific pattern to a newly created filesystem and afterwards using `btrfs inspect-internal -t raid-stripe $SCRATCH_DEV_POOL` to verify the placement and the layout of the metadata. The md5sum of each file will be compared as welli after a re-mount of the filesystem. --- Changes in v2: - Re-ordered series so the newly introduced group is added before the tests - Changes Filipe requested to the tests. - Link to v1: https://lore.kernel.org/r/20231204-btrfs-raid-v1-0-b254eb1bcff8@xxxxxxx --- Johannes Thumshirn (7): fstests: doc: add new raid-stripe-tree group common: add filter for btrfs raid-stripe dump btrfs: add fstest for stripe-tree metadata with 4k write btrfs: add fstest for 8k write spanning two stripes on raid-stripe-tree btrfs: add fstest for writing to a file at an offset with RST btrfs: add fstests to write 128k to a RST filesystem btrfs: add fstest for overwriting a file partially with RST common/filter.btrfs | 14 +++++++ doc/group-names.txt | 1 + tests/btrfs/302 | 53 ++++++++++++++++++++++++++ tests/btrfs/302.out | 58 ++++++++++++++++++++++++++++ tests/btrfs/303 | 58 ++++++++++++++++++++++++++++ tests/btrfs/303.out | 82 ++++++++++++++++++++++++++++++++++++++++ tests/btrfs/304 | 56 +++++++++++++++++++++++++++ tests/btrfs/304.out | 75 +++++++++++++++++++++++++++++++++++++ tests/btrfs/305 | 53 ++++++++++++++++++++++++++ tests/btrfs/305.out | 65 ++++++++++++++++++++++++++++++++ tests/btrfs/306 | 56 +++++++++++++++++++++++++++ tests/btrfs/306.out | 106 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 12 files changed, 677 insertions(+) --- base-commit: baca8a2b5cb6e798ce3a07e79a081031370c6cb8 change-id: 20231204-btrfs-raid-75975797f97d Best regards, -- Johannes Thumshirn <johannes.thumshirn@xxxxxxx>
