Linux 2849 Published by

Linus Torvalds has announced the release of the first release candidate for Linux kernel 6.1 for testing.



Linux kernel 6.1-rc1 released

You all know the drill: it's Sunday afternoon, the two weeks of merge window are over, and now we're supposed to start calming things down.

This isn't actually shaping up to be a particularly large release: we "only" have 11.5k non-merge commits during this merge window, compared to 13.5k last time around. So not exactly tiny, but smaller than the last few releases. At least in number of commits.

That said, we've got a few core things that have been brewing for a long time, most notably the multi-gen LRU VM series, and the initial Rust scaffolding (no actual real Rust code in the kernel yet, but the infrastructure is there).

And hey, this merge window was full of surprises for other reasons too - my main machine was basically out of action for a couple of days because it suddenly started showing memory problems, and it took me a couple of days to get that sorted out (to a large degree because it was unexpected and I started out blaming a kernel bug for the memory corruption). All sorted out now, but it caused some frustration.

Talking about frustration, let me just say that after I got my machine sorted out and caught up with the merge window, I wass somewhat frustrated with various late pull requests. I've mentioned this before, but it's _really_ quite annoying to get quite a few pull requests in the last few days of the merge window.

Yes, the merge window is two weeks, but that's very much to allow me time to look things over, not "two weeks to hurriedly put together a branch that you send Linus on Friday of the second week". The whole "do an all-nighter to get the paper in the day before the dealine" is something that should have gone out the window after highschool. Not for kernel development.

The rule is that things that get sent to me should be ready *before* the merge window opens, not be made ready during the merge window. With some slack for "life happens", of course, but I really get the feeling that a few people treat the end of the merge window as a deadline, missing the whole "it was supposed to be ready before the merge window".

You know who you are.

Anyway, it's not the first time I've said this, I doubt it will be the last. But maybe more people could take it to heart, ok?

Enough kvetching, let's get this party calmed down. The merge window may not be the biggest ever, but it's certainly big enough that the shortlog is much too big to post, and below is just my usual merge log. For all the gory details, please refer to the git tree.

Please get the testing started,

Linus
