This is duplicated across several tests now. Perhaps this should be factored now into a _requires_fssum helper (separate patch is fine)?

you should be able to use _check_scratch_fs() here. I note that the btrfs path does not unmount the scratch device, so you should update it to do so (like _check_xfs_filesytem does) and then _check_scratch_fs() will just Do The Right Thing.

All done in V2 (same for the other test).
For the require_fssum() function, I made a patch on top of these 2 so that it updates all existing btrfs tests that need fssum ("[PATCH]
xfstests: add function _require_fssum()").
Thanks for the good suggestions Dave.

V2: Some cleanup as suggested by Dave Chinner. Use _check_scratch_fs() and
removed redundant stderr redirection when calling fssum via run_check.
