I agree with this -- except that I think few if any device specific
C header files should be exposed to userland at all.
Indeed. I think this is why we have the distinction between
sys/XXXXio.h (or sys/XXXX.h), which defines structures and interfaces
dev/XXXXvar.h which is used internally by a driver.
It seems to me that headers shared between userland and the kernel are
candidates for sys/sys.
