While last week’s RC3 release of Linux kernel 4.15 was bigger than expected, it would appear that the RC4 build is “about average size,” according to Linus Torvalds. This is a good thing, of course, signaling that the final Linux 4.15 kernel release could land in time, but the winter holidays could stand in its way after all. As promised, the suspend/resume handling is now fixed in RC4, which finally removes the cross-locking debug code that caused problems to kernel developers. Also, it contains that usual driver updates, filesystem fixes, networking and tooling improvements. Check out the appended shortlog for more details on the changes.
