    FS-Cache might. CacheFiles probably doesn't.

    There've been discussions about a separate caching backend to deal with
    non-rotating media such as large chunks of battery-backed RAM or flash.
    FS-Cache might make sense in such a situation as these could be accessed in
    other ways (such as through MTD or even directly).

    I'll make CONFIG_CACHEFILES dependent on CONFIG_BLOCK.
