    memcg: destroy memcg caches · 1f458cbf
    Glauber Costa 提交于
    Implement destruction of memcg caches.  Right now, only caches where our
    reference counter is the last remaining are deleted.  If there are any
    other reference counters around, we just leave the caches lying around
    until they go away.
    
    When that happens, a destruction function is called from the cache code.
    Caches are only destroyed in process context, so we queue them up for
    later processing in the general case.
