Linux 2764 Published by

Linus Torvalds has announced the release of the second release candidate for Kernel 6.6, exactly 32 years after the initial release of Kernel 0.01.



Linux kernel 6.6-rc2 released

Another week, another -rc.

I think the most notable thing about 6.6-rc2 is simply that it's exactly 32 years to the day since the 0.01 release. And that's a round number if you are a computer person.

Because other than the random date, I don't see anything that really stands out here. We've got random fixes all over, and none of it looks particularly strange. The genpd -> pmdomain rename shows up in the diffstat, but there's no actual code changes involved (make sure to use "git diff -M" to see them as zero-line renames).

And other than that, things look very normal. Sure, the architecture fixes happen to be mostly parisc this week, which isn't exactly the usual pattern, but it's also not exactly a huge amount of changes.

Most of the (small) changes here are in drivers, with some tracing fixes and just random things. The shortlog below is short enough to scroll through and get a taste of what's been going on.

Please go test,

Linus
