The rest of the 6.3 merge window

https://bugs.gentoo.org/900857 has been in filibuster purgatory until this year, and only because the kernel community's action here has pressured them into doing something. That's very much the tip of the iceberg, parts of the story are in 542498, 606562, 828973 and 895856 (and others, which I've long since lost track of).

Unfortunately nobody's done a cohesive writeup of any of it, and to do so would require deep-diving ~5 years of bugzilla, the -project mailing list (which doesn't seem to be archived anywhere with a usable UI), and… parts of the forums that were deleted outright a few years ago. That's another story entirely, but the short version is that a Large Corporate Sponsor decided it was a bad look for the distro to have no code of conduct or copyright attribution.
