Which clean-up exactly?

The only duplication I see here is that ext2load/fatload could be
modified to simply call into do_fsload. That'd be pretty simple, I
think, assuming the behaviour change was OK (e.g. fatload would
suddenly support either FAT or ext2*), and that cmd_fs.c and fs.c
would both always be pulled in.

Re: refactoring of the interface to the filesystem code: I'm curious
what the DM-related plans are for filesystems. It seems that any such
refactoring would be part of that work. Unfortunately I haven't been
paying any attention to who might be proposing doing what and when
there. Would it be appropriate to defer any fs-related API changes
until any DM+fs rework went it to avoid conflicts or duplicate work?
