Linux 6.17 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.17 has just been released on LKML: No huge surprises this past week, so here we are, with kernel 6.17 pushed out and ready to go. Below is the shortlog for just the last week – not the full 6.17 release – as usual. It’s not exciting, which is all good. I think the biggest patch in there is some locking fixes for some bluetooth races that could cause use-after-free situations. Whee – that’s about as exciting as it gets. Other than that, there’ the usual driver fixlets (GPU and networking dominate as usual, but “dominate” is still pretty small), there’s some minor random other driver updates, some filesystem noise, and core kernel and mm. And some selftest updates. This obviously means that the merge window for 6.18 will open tomorrow, and I already have four dozen pull requests pending. Thanks to the proactive people – you know who […]
