	fn(dest, src)

is a well-known C idiom which the kernel went and broke in lots of places :(

It maps nicely onto

	dest = src

as a mnemonic.

But given that the compiler will reliably barf if they are backwards
it's a minor thing.

(strong objections would save me a lot of work (looks hopefully at
inbox))).
