Still not sure this is a good idea for a couple of reasons: 1. We already have lots of special cases with skb's (frags and fraglist), and skb's travel through a lot of different parts of the kernel. So any new change like this creates lots of exposed points for new bugs. Look at cases like MD5 TCP and netfilter, and forwarding these SKB's to ipsec and ppp and ...
2. SKB's can have infinite lifetime in the kernel. If these buffers come from a fixed size pool in an external device, they can easily all get tied up if you have a slow listener. What happens then? -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
