Hi Darrick,

Thanks very much for the patch. I applied it to the git-master and built
e2fsprogs. The new "make check" test for "f_convert_bmap_sparse" passes,
and indeed my test-case script now passes.
However the test for "f_detect_junk" is failing for me:

I think the expect test maybe just needs updating.

I will now try the patched e2fsck on the full data-migration process I'm
doing and report back. This will take a few hours.

Kind Regards,
Marc
