Purpose of an AF_KERN socket: pass data into the kernel, have it do
		something, then return the result.
Purpose of a system call: pass data into the kernel, have it do
		something, then return the result.

Of course, using socket/read/write results in 3 system calls instead of 1.
and it's a bit unwieldy.
What's the benefit, other than perhaps being able to use the protocol
arg in socket() to specify a section of the kernel that the request
is going to?
