Linus Torvalds has released Linux 6.15-rc6 today with hopes of releasing Linux 6.15 stable in two weeks.

This week merged for Linux 6.15 and found in 6.15-rc6 are a fix for some TLB flushes accidentally being skipped, support for a few more gaming controllers within the XPad driver, and addressing that AMD CPU performance regression I noted last month. Plus various other small bug/regression fixes throughout.

Linus Torvalds commented in the 6.15-rc6 announcement:

"Everything still looks fairly normal - we've got a bit more commits than we did in rc5, which isn't the trend I want to see as the release progresses, but the difference isn't all that big and it feels more like just the normal noise in timing fluctuation in pull requests of fixes than any real signal.

So I won't worry about it. We've got another two weeks to go in the normal release schedule, and it still feels like everything is on track."

Linus also shared his latest thoughts on keyboards in abandoning a quiet low-profile keyboard back for his MX Cherry switch-based keyboard:

"In unrelated news: I finally gave up on my attempt at using a quieter low-profile keyboard: I gave it half a year thinking I'd get used to it, but I'm back to the noisy clackety-clack of clicky blue cherry switches. It seems I need the audible (or perhaps tactile) feedback to avoid the typing mistakes that I just kept doing.

I'm not sure why I even tried, since it's not like I'm in some office where the noise of my keyboard can disturb others.

I mention this only in case people have reacted to my typos. Or maybe it's just me, and I'm just conveniently blaming the keyboard."

In any event there are many great Linux 6.15 features to be found in this kernel debuting in late May.
