I almost missed it, but 2.6.16 shipped with an NFS update that makes me happy. It’s now possible to kill those nasty processes hung on RPC calls when your NFS mount point goes away. Previously, you could umount -l with some success, but this is better.
Additionally, there is now support for the IFB device, or Intermediate Functional Block (I just love these names), which provides functionality similar to IMQ and is mainlined. Should prove useful for ingress shaping to multiple interfaces on a router or when the router itself is a significant consumer of downstream data.
I guess it’s finally time to configure ingress shaping on my router, limited as it may be, since shaping traffic you’ve already received relies entirely on the transport layer noticing that you’re dropped packets.
