[PATCH v7 0/10] fstests: add tests for btrfs' raid-stripe-tree feature

[Anand Jain <anand.jain@oracle.com>]

Changes in v7:
- Fixed trailing whitespace in the .out files
- Fixed the following test statement in 30[4-8]:
     test _get_page_size -eq 4096
- Link to v6: https://lore.kernel.org/r/20231213-btrfs-raid-v6-0-913738861069@wdc.com

--- original cover page from Johannes ----
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/20231207-btrfs-raid-v5-0-44aa1affe856@wdc.com

Changes in v5:
- add _require_btrfs_free_space_tree helper and use in tests
- Link to v4: https://lore.kernel.org/r/20231206-btrfs-raid-v4-0-578284dd3a70@wdc.com

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/20231205-btrfs-raid-v3-0-0e857a5439a2@wdc.com

Changes in v3:
- added 'raid-stripe-tree' to mkfs options, as only zoned raid gets it
  automatically

- Link to v2: https://lore.kernel.org/r/20231205-btrfs-raid-v2-0-25f80eea345b@wdc.com
