Remember, mmapped pages are not written to swap. Affected are all
partitions mounted rw. And it is not limited to disks. There are also
nfs, nbd, i-scsi ...
I am sure the swsusp people will really appreciate the added
necessity to first compute the set of devices that need to run.
If you want to design a model acceptable to all subsystems _and_
the core power management system, it needs to be simple above
