Regression fixes?

Note that if people stopped introducing regressions to the kernel, we
might actually be able to release the final version after -rc6 or even
earlier.

There's nothing which says that we MUST have -rc7, -rc8, -rc9
releases.  If we were actually disciplined in our testing and in what
we push into Linus's tree, we might actually be able to go to a
two-month release cycle, or perhaps even slightly shorter.

But if people insist on trying to fix bugs, and those bugs fixes
introduce regressions, then we end up with a longer release cycle,
which causes people to want to stuck more bug fixes, or worse, even
some feature commits late into the development cycle, and it becomes a
vicious cycle with releases taking longer and longer.
