Oh, damn.

It wasn't addded by me, though, and if somebody wants to change the name
to "Frodo Rabbit", I wouldn't holler loudly.

Let's make it policy that we _never_ print out annoying messages that have
no useful purpose for debugging or running the system, ok?

"Informational" messages aren't informational, they're just annoying, and
they hide the _real_ stuff.

Things like version strings etc sound useful, but the fact is that the
only _real_ problem it has ever solved for anybody is when somebody thinks
they install a new kernel, and forgets to run "lilo" or something. But
even that information you really get from a simple "uname -a".

Do we care that when you boot kernel-2.4.5 you get "net-3"? No. Do we care
that we have quota version "dquot_6.4.0"? No. Do we want to get the
version printed for every single driver we load? No.

If people care about version printing, it (a) only makes sense for modules
and (b) should therefore maybe be done by the module loader. And modules
already have the MODULE_DESCRIPTION() thing, so they should NOT printk it
on their own. modprobe can do it if it wants to.

So let's simply disallow versions, author information, and "good status"
messages, ok? For stuff that is useful for debugging (but that the driver
doesn't _know_ is needed), use KERN_DEBUG, so that it doesn't actually end
up printed on the screen normally.

Authors willing to start sending me patches?
