Please for all that is good in the world, let the Linux foundation invest the majority of their funds in the Linux kernel first. Then please have a marketing budget bigger than what's left.. A paltry 2% of their funding going to kernel stuff is an absolute joke.
The kernel also badly needs to be rewritten in rust. Not all at once but piecemeal. The rust tooling is lightyears ahead of whatever is being used now, getting into a rust project is also so much easier. There's another project, the name of which I can remember, doing a rewrite and building it is a simple as cargo build. Seriously, that's the level of simplicity I want, not whatever bullshit I have to do now and follow a guide, take my own notes on how to make it work on my specific distro, fail a few times, and stare at unreadable GCC errors.
Also please please please stop using a mailing list (or at least make it optional). Holy moly are you losing a bunch of next gen devs through that. Regardless of how controversial the CoC was, it finally changed the tone a little, which is nice, but mailing lists are seriously archaic. The absolute minority uses them. It's another big thing hampering kernel development (at least to me). They are a terrible experience through and through that make it difficult to follow discussions, diffs difficult to read and interact with (leave comments on lines and respond to them), and spams the inbox.
Please let kernel development move into this century.
