Could you please also change size to blocksize, so it's more obvious
what the parameter to dx_make_map() and dx_pack_dirents(), and
resubmit an updated patch to Andrew?  That will make it much more
obvious what is going on.

I'll make the same changes to the patch destined for the ext4 tree myself.

Thanks, regards,
