[v6,0/9] fstests: add tests for btrfs' raid-stripe-tree feature

Message

Johannes Thumshirn Dec. 13, 2023, 11:35 a.m. UTC

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 well after a re-mount of the
filesystem.

Changes in v6:
- require 4k pagesize for all tests as output depends on page size
- Add Filipe's Reviewed-by
- Link to v5: https://lore.kernel.org/r/[e-mail]

Changes in v5:
- add _require_btrfs_free_space_tree helper and use in tests
- Link to v4: https://lore.kernel.org/r/[e-mail]

Changes in v4:
- add _require_btrfs_no_compress to all tests
- add _require_btrfs_no_nodatacow helper and add to btrfs/308
- add _require_btrfs_feature "free_space_tree" to all tests
- Link to v3: https://lore.kernel.org/r/[e-mail]

Changes in v3:
- added 'raid-stripe-tree' to mkfs options, as only zoned raid gets it
  automatically
- Rename test cases as btrfs/302 and btrfs/303 already exist upstream
- Link to v2: https://lore.kernel.org/r/[e-mail]

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/[e-mail]
