*nod*
Most of the special mkfs sauce that is used by XFS specific tests
simply has not been written for other filesystems. The hard coded
results from _filter_mkfs are just there so that generic tests that
use dbsize/isize mostly work.
So if want you to add this "reflect reality" functionality for ext4
you are more than welcome to do it. :)
Cheers,
Dave.
