Ah, right, I said that was during the discussion about the commit I
quoted above. You convinced me that we shouldn't cater for special
cases like this and instead iterate mkfs/mount configurations.
On that basis I committed your patch to remove the special cases
from generic/017.

/me shakes his head, wonders how other maintainers stay sane
I think the test should still be generic and block size independent,
but if you want to force ext4 to turn off the extents flag, then
use something like this:
[ "$FSTYP" = "ext4" ] && MKFS_OPTIONS="-O ^extents $MKFS_OPTIONS"
Cheers,
Dave.
