Please, no, not -another- new and just a bit different "fill
filesystem" function.
There's already been one added recently in test 256 which I
commented at the time could use _populate_fs, and I said the same
thing in my original review of this series, too.
So please modify the _populate_fs function to do what you need.
Cheers,
Dave.
