Actually, having read through that code...  It's not too scary; r/w
support would've been much more hairy, but this is just r/o.  We
probably don't need to move that sucker at all.

As for befs_get_block(), I'd suggest
	* taking the range checks for block number into its ->bmap()
(just check against the file size and return 0 if it doesn't fit)
	* turning the check for create != 0 into BUG_ON(create)
	* making the befs_fblock2brun() failure quiet - the sucker
will complain itself, just return that -EFBIG and be done with that.
