Huh what

since when?

AFAIR this is one thing Linus has been adamant about for a long long time,
do not add the complexity of swappable kernel code to the kernel.

There was once upon a time the user space nfs server, however the nfs file
system in the linux kernel has always been kernel space, of course I guess
someone could implement User Space NFS with FUSE or something easily
maybe... <eg>
