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.

Hasn't run_check already redirected everything to $seqres.full?

_check_scratch_fs() here too.
