The best Userspace-kernelspace-Userspace transfer thing is soket.
Unix or TCP/UDP sockets API is avaible from kernel space.
You should use it...
Sockets suck for the kind of application relayfs is used for. Try
running LTT on sockets, for example, and let me know what type of
performance you get. For simple transfers, maybe, but for real
high-speed, large scale data transfers, sockets just don't cut it.
That's where relayfs is most useful.
