Hi, 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.
