Subject[PATCH v3] vsock/virtio: free packets during the socket release
Date
When the socket is released, we should free all packets
queued in the per-socket list in order to avoid a memory
leak.

Signed-off-by: Stefano Garzarella <sgarzare@redhat.com>

This patch was in the series "[PATCH v2 0/8] vsock/virtio: optimizations
to increase the throughput" [1]. As Stefan suggested, I'm sending it as
a separated patch.

v3:
- use list_for_each_entry_safe() [David]
