You must be looking at old sources.  Most of the kernel has been
converted, but it is still a work in progress.  There's very little
gain for the risk that something subtle that's different between K&R
and ANSI causes breakage...  The risk is much lower these days since
we insist on proper prototypes...

Nearly all of the kernel has been converted.  The parts that remain
are the less widely travelled paths through the code.

phk used to have a /jkh/ page, or Junior Kernel Hacker page.  Don't
know if that's still that way or not.
