    net: Make account struct net to memcg · 30855ffc
    Kirill Tkhai authored
    The patch adds SLAB_ACCOUNT to flags of net_cachep cache,
    which enables accounting of struct net memory to memcg kmem.
    Since number of net_namespaces may be significant, user
    want to know, how much there were consumed, and control.
    
    Note, that we do not account net_generic to the same memcg,
    where net was accounted, moreover, we don't do this at all (*).
    We do not want the situation, when single memcg memory deficit
    prevents us to register new pernet_operations.
    
    (*)Even despite there is !current process accounting already
    available in linux-next. See kmalloc_memcg() there for the details.
