    mm: add context argument to shrinker callback · 7f8275d0

    The current shrinker implementation requires the registered callback
    to have global state to work from. This makes it difficult to shrink
    caches that are not global (e.g. per-filesystem caches). Pass the shrinker
    structure to the callback so that users can embed the shrinker structure
    in the context the shrinker needs to operate on and get back to it in the
    callback via container_of().
