[PATCH v2 1/8] vsock/virtio: limit the memory used per-socket
Since virtio-vsock was introduced, the buffers filled by the host
and pushed to the guest using the vring, are directly queued in
a per-socket list avoiding to copy it.
These buffers are preallocated by the guest with a fixed
size (4 KB).
The maximum amount of memory used by each socket should be
controlled by the credit mechanism.
The default credit available per-socket is 256 KB, but if we use

[PATCH v2 0/8] vsock/virtio: optimizations to increase the throughput
While I was testing this new series (v2) I discovered an huge use of memory
and a memory leak in the virtio-vsock driver in the guest when I sent
1-byte packets to the guest.
These issues are present since the introduction of the virtio-vsock
driver. I added the patches 1 and 2 to fix them in this series in order
to better track the performance trends.
