Actually this is an understatement. Every feature (and I do mean _every_) that went from -rt into mainline, undertook 3 or more rewrites before it was acceptable for mainline. And every time, the end result made the -rt patch set better as a whole. Not to mention, that a lot of the early stuff also cleaned up mainline. You can't have Real-Time without having a clean kernel. And as you stated, a lot of those patches to clean up the kernel, no one even knew that the real reason was to help the -rt patch set. They were well disguised Trojan horses. Darn, it looks like you are onto our scheme. -- Steve
