I would too. Andries's patches look like the right thing to do, so far
as I've seen. But there are larger, social issues, that probably need
to be answered first (like convincing Linus and others that this is
really needed).

I haven't seen a patch yet, to really know what will be necessary. But
for one, a lot of drivers have static arrays where they just "know" that
there can't be more than 256 minors under their control.

As a small example, look at all of the static arrays of struct
tty_struct * for all of the tty drivers :(
