    Subject[RFC][PATCH 0/4] VM deadlock prevention -v4

    here the latest effort, it includes a whole new trivial allocator with a
    horrid name and an almost full rewrite of the deadlock prevention core.
    This version does not do anything per device and hence does not depend
    on the new netdev_alloc_skb() API.

    The reason to add a second allocator to the receive side is twofold:
    1) it allows easy detection of the memory pressure / OOM situation;
    2) it allows the receive path to be unbounded and go at full speed when
    resources permit.

    The choice of using the global memalloc reserve as a mempool makes that
    the new allocator has to release pages as soon as possible; if we were
    to hoard pages in the allocator the memalloc reserve would not get
    replenished readily.
