From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linus responds to Hellwig - "the pull request you objected to DID NOT TOUCH THE DMA LAYER AT ALL... if you as a maintainer feel that you control who or what can use your code, YOU ARE WRONG." (lore.kernel.org)

Hellwig is the maintainer of the DMA subsystem. Hellwig previously blocked rust bindings for DMA code, which in part resulted in Hector Martin from stepping down as a kernel maintainer and eventually Asahi Linux as a whole.

(rightfully) does not like mixed language codebases for projects as large and important as Linux

You make it sound like it's a matter of taste rather than a technical one (and I suspect it actually might be just about taste in the end)

Its a little of column A, little of column B type situation.

Yes, some of it is his taste, but that taste is coming from a technical place. Primarily long term maintainability of the project.

I realize what Linus came out and said outlines that no code is entering Christoph's part of the project, but Christoph is playing goalie and needs to make sure that never happens in order to keep everything working correctly for a very long time.

Maybe the DMA module gets rewritten completely in Rust one day, but until then, rust modules interfacing with a C-only component seems to be the best for long-term maintenance.
