In short, we could use regular files for the suspend in the same way in which we
use them for swap. Namely, we could bmap() a file and create a map of it
(eg. with extents) that would be used for accessing the corresponding disk
sectors at the block device level. Then, to be able to read the image the
resume code would have to be provided with the number of the sector in which
the suspend image header is located.
However, we already have code that allows us to use swap files for the suspend
and turning a regular file into a swap file is as easy as running 'mkswap' and
'swapon' on it.
