Linus Torvalds Releases Linux Kernel 4.0 RC5 with Several Updated Drivers, you can update or upgrade this kernel on Ubuntu 15.04 vivid Vervet, ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr (LTS) and Linux Mint 17.1 Rebecca, Linux Mint 17 Qiana
Linux kernel is the essential part of any Linux operating system. It is responsible for resource allocation, low-level hardware interfaces, security, simple communications, basic file system management, and more. Written from scratch by Linus Torvalds (with help from various developers), Linux is a clone of the UNIX operating system. It is geared towards POSIX and Single UNIX Specification compliances.
Today, March 23, Linus Torvalds had the pleasure of announcing the fifth Release Candidate (RC) version of Linux kernel 4.0, one of the most highly anticipated Linux technologies of 2015. Therefore, we’re announcing that Linux kernel 4.0 RC5 is now available for download and testing (see download link at the end of the article).
According to the appended shortlog, Linux kernel 4.0 RC5 includes mostly driver updates for GPU, USB, HID, networking, sound, pinctrl, input, etc., several architecture updates for ARM, ARM64, x86, and SPARC, various fixes to the btrfs file system, and some networking fixes.
“So rc5 is almost exactly the same size as rc4 was. I'd be happier if the rc's were shrinking,” says Linus Torvalds. “There's nothing particularly worrisome going on, although I'm still trying to think about the NUMA balancing performance regression. It may not be a show-stopper, but it's annoying, and I want it fixed. We'll get it, I'm sure.”
