Linux Kernel 6.10 Released with Many New Hardware Support

Last updated: July 15, 2024 — 2 Comments

Linux Kernel 6.10 was finally released a day ago on this Sunday. Linus Torvalds announced on this page:

“So the final week was perhaps not quote as quiet as the preceding ones, which I don’t love – but it also wasn’t noisy enough to warrant an extra rc. And much of the noise this last week was bcachefs again (with netfs a close second), so it was all pretty compartmentalized.

In fact, about a third of the patch for the last week was filesystem-related (there were also some btrfs latency fixes and other noise), which is unusual, but none of it looks particularly scary.”
