Playing with rlimit on data path, transparently to the application in this way
looks strange to me, I suspect this has unexpected security implications.
Further, applications may have other uses for locked memory
besides mpassthru - you should not just take it because it's there.
Can we have an

This example is made on ixgbe driver which using napi_gro_frags().
It can get buffers from guest side directly using netdev_alloc_page()

We provide an zero-copy method which driver side may get external
buffers to DMA. Here external means driver don't use kernel space
to allocate skb buffers. Currently the external buffer can be from
guest virtio-net driver.
The idea is simple, just to pin the guest VM user space and then
