Sock ioctls don't required a /dev entry, do they?

oh, well, I suppose there you go, although it might be nice
to have a /dev/pci and mmap that instead... but see below....

Oh, no- I was hoping you wouldn't have to do that. I ran into this
too and I got drochner's starts to elfify lkm and I haven't got
time to do this any time soon. Never mind.

Note thought that mmap of a device on an alpha is not a trivial
matter. As soon as CGD sees this or Jason reads his mail on the
way to IETF you'll probably get 1.25 of an earful about it.

There is no hatred so deep as close family members (siblings) who seem to
hate each other so much that you'd think they had slept with each other's
spouses.
