I found a bunch more tests in the xfs/ directory that try to create specific metadata layouts on the data device, either because they're fuzz tests or because they're testing specific edge cases of the code base. Either way, these test need to override '-d rtinherit' in the MKFS_OPTIONS, so do that with _xfs_force_bdev. Signed-off-by: Darrick J.
