What uses it, and to do what exactly? Is it used by nfs server code, or by the client code, or both? Is it a way for userspace to talk to the kernel, or for the kernel to talk to itself? Is it used at mount time, or during filesystem operation? I'm interested in giving this patch series a much more thorough review, but I can't figure out what the subsystem it's modifying actually _is_. (Maybe this is something to do with filesystems/nfs/rpc-cache.txt?) Rob
