Were these even considered when the FreeBSD vnode stacking implementation was done? The NFS default op is the one returning the NOT SUPPORTED error. A bypass op would allow you to stack on top of an out-of-kernel layer which could then be layered on a utok layer to cross the boundary again. I guess the fs memory allocation architecture is not compatible with this. Debugging in userland would sure be cool, when you're satisfied take away the transport layers and you're back in the kernel. Regards, Mike Hancock
