Linux Kernel 4.9.4 is Available For Ubuntu 16.04, 16.10 and Linux Mint 18

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.

Includes powerful features

Linux provides users with powerful features, such as true multitasking, multistack networking, shared copy-on-write executables, shared libraries, demand loading, virtual memory, and proper memory management.

Initially designed only for 386/486-based computers, now Linux supports a wide range of architectures, including 64-bit (IA64, AMD64), ARM, ARM64, DEC Alpha, MIPS, SUN Sparc, PowerPC, as well as Amiga and Atari machines.

If you were afraid that your patch did not land in Linux 4.9, which is currently the most advanced stable kernel branch available for GNU/Linux distributions, or if you thought that your device didn't yet receive the right drivers, think again, because Linux kernel 4.9.4 is full of goodies. Yes, again, but this time the patch is a little smaller and fixes a total of 59 files, with 507 insertions and 205 deletions.

"I'm announcing the release of the 4.9.4 kernel. All users of the 4.9 kernel series must upgrade. The updated 4.9.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.9.y and can be browsed at the normal kernel.org git web browser: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary," said Greg Kroah-Hartman.

Networking improvements all over, some ARM and ARM64 changes

From the appended shortlog, we can notice that the major changes in the Linux 4.9.4 patch are mostly networking improvements, both for the drivers stack, which received better support for Realtek Wi-Fi cards and Mellanox (mlx5) Ethernet adapters, and the networking stack, bringing various fixes to the IPv4, IPv6, SCTP, and SunRPC protocols, as well as the Distributed Switch Architecture (DSA) subsystem.

Numerous ARM and ARM64/AArch64 changes are also present in the Linux 4.9.4 kernel, along with small bug fixes to the PowerPC (PPC) and x86 hardware architectures. Other than that, there's a quirk for the Plantronics BT600 high-fidelity Bluetooth USB adapter, and some minor fixes to the Intel i915 graphics driver. The Linux kernel 4.9.4 source archive is now available for download from kernel.org.
