After reading so much out-of-date on-line document, which i can not identify, i got several questions regarding the FAQ:http://kernelnewbies.org/MigratingInProgress/FAQ.

Q1. Is the kernel-janitors still active and welcomed by mainline kernel.
Q2. Does this project only aim to linux-2.x kernel, not any current latest kernel--linux-3.x kernel?
Q3. "Be sure to check -mm and -kj trees to see if someone already did that. ". Is it still valid? If yes, where to find the -mm tree(seems replaced by linux-next),  http://coderock.org/kj/ is the -kj tree, right?

Best Regards,
Biao
