Our usage is mainly kernel-focused but not the tool. It is C-program focused
and we have used it on other programs like Wine, OpenSSL, VLC. Others
use it on other projects like Davecot or close-source projets.
So, IMHO Coccinelle should no be part of Linux.

Integrating kernel-focused SmPL scripts is on the other hand a great idea
to check the kernel and to ease kernel developer life.
It is what have been done so far. It is certainly possible to improve that,
at least by adding more and more scripts.

At every RC, we push the Coccinelle code on github. Using git-submodule
seems the way to go thus. Moreover, it will ease the maintenance of
scripts as we may assume users have one of the latest versions.
