I don't understand. During suspend, you just need a list of blocks to write to from the swapfile. You can get that list before starting the actual suspend, so that writing doesn't imply any filesystem activity.
When you're resuming, you just need a list of which disk blocks to resume from. Can't that list be stored in a few blocks of the swapfile itself, with the only critical parameter being the first block number to resume from?
(A bit like LILO has a map file containing the list of blocks which contain the kernel to boot.)
