The longstanding nfsd has always run in user mode; since NFS does so vastly
much access "kernel stuff," it represents an example of something where there
would indeed be performance benefits from pushing it from user space into
the kernel.  That is what the BSD's have long done, and is the reason why
they have had better NFS performance than Linux.

What is experimental is the notion of running it as a kernel module
rather than as a user-space daemon.
