#note to myself, not throughly thought out...
Useful #kernel feature for #hibernate might be a file that would tell the number of pages required for hibernate.
The "O-figure" for hibernate is AFAIK O(n+sqrt(n)) but exact number is dependent on kernel internals but in theory could be calculated by simulating the process without committing.
Instead of swap it might also be useful to have "spare" volume of ~100 GB for doing hibernate and e2scrub type of operations, which could have its own design for encryption etc. Swap for swapping overcommitted memory more than few at most GiB is not that useful these days.
