Stop right there.
This is *not* about some arbitrary "30-year backwards compatibility".
This is about your patch BREAKING EXISTING BINARIES.
So stop the f*&^ing around already. The patch was shown to be broken,
stop making excuses, and stop blathering.
End of story. Binary compatibility is more important than *any* of
your patches. If you continue to argue anything else or making
excuses, I'm going to ask people to just ignore your patches entirely.
Seriously. Binary compatibility is *so* important that I do not want
to have anything to do with kernel developers who don't understand
that importance. If you continue to pooh-pooh the issue, you only show
yourself to be unreliable. Don't do it.
Dammit, I'm continually surprised by the *idiots* out there that don't
understand that binary compatibility is one of the absolute top
priorities. The *only* reason for an OS kernel existing in the first
place is to serve user-space. The kernel has no relevance on its own.
Breaking existing binaries - and then not acknowledging how horribly
bad that was - is just about the *worst* offense any kernel developer
can do.
Because that shows that they don't understand what the whole *point*
of the kernel was after all. We're not masturbating around with some
research project. We never were. Even when Linux was young, the whole
and only point was to make a *usable* system. It's why it's not some
crazy drug-induced microkernel or other random crazy thing.
Really.
Linus
