    You might check the work/papers by Niels Provos on encrypted swap.

    We've been working on this problem for our NCryptfs. To provide a
    comprehensive solution, we have to also handle swap. Luckily in Linux,
    there are specific VOPs and APIs that make it easy to hook a crypto f/s w/
    the swap.
