Nice, short, _clear_ and no - a loop that counts down instead of
up is not difficult at all.
Testing "i--" instead of "i >= 0" is also something I consider trivial,
even though I don't code that much. If this is among the worst you
see, then the kernel source must

then you can turn the trend and keep linux the way you want it.
If you don't - those that do contribute will get to shape linux
the way they like. Whoever makes linux gets to decide.
Another way is to stay with linux 2.4. You won't get any
new stuff that way, but no new GPL surprises e
way is the recommended
way of working anyway. It isn't merely a way to keep your
code away from the GPL - you always want a small kernel.

Other keyboard(s) become useful once the linux comes up with
its event interface. You then have one set of LEDS per keyboard.

Unfortunately, that don't stop people from trying - it is hard to
see what's going on in a closed module. Now if breaking the law
this way can be made more difficult then that is a good thing. Fewer
vendors will then try. They will make closed modules
ion where 90% of the drivers necessary to
run a linux kernel are proprietary. It does so by ensuring that the
proprietary vendors access a limited API, unless they take
a lot of cumbersome extra steps like maintaining their own
"protection-free" kernel. Which they certainly can do under

illegal.
So a vendor using the \0 trick is on very shaky ground.
He has another option - to patch out the test. But he
don't want that, for then he have to distribute a kernel,
not only a module.

the boss ask for a file - just write that userspace helper
because that is the way it is done on linux. No conflict there.
