Git is the change-tracking tool used by the Linux kernel developers, originally written by Linus Torvalds. This mailing list is where git development happens.

A mailing list for Linux filesystem development.

Kernelnewbies are a community of people that improve or update their Kernels and of aspiring Linux kernel developers and more experienced developers willing to share their knowledge. We help each other learn how the Linux kernel works and occasionally discuss other operating system kernels.

A mailing list for Linux networking user questions.

Sparse, the semantic parser, provides a compiler frontend capable of parsing most of ANSI C as well as many GCC extensions, and a collection of sample compiler backends, including a static analyzer also called "sparse". Sparse provides a set of annotations designed to convey semantic information about types, such as what address space pointers point to, or what locks a function acquires or releases. Linus Torvalds started writing Sparse in 2003, initially targeting issues such as mixing pointers to user address space and pointers to kernel address space. As of 2006, Josh Triplett now maintains Sparse.

An informal project to get experienced developers to mentor new developers and coach them on the best ways to get their code ready for submission.
