[PATCH v2 0/7] fstests: add tests for btrfs' raid-stripe-tree feature

[Johannes Thumshirn <johannes.thumshirn@wdc.com>]

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@wdc.com
