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.
“I’m announcing the release of the 4.8.15 kernel. All users of the 4.8 kernel series must upgrade,” said Greg Kroah-Hartman in the release announcement for Linux kernel 4.8.15. “The updated 4.8.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.8.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.”
Users of the Linux 4.4 LTS and 4.8 kernels must update immediately
According to their appended shortlogs and the diffs since the previous versions, Linux kernels 4.8.15 and 4.4.39 LTS are here to introduce a bunch of architecture updates, for PowerPC (PPC), SPARC, ARM64, x86, PA-RISC, and m68k, improve the ACPI, SCSI, crypto, DAX, and NVDIMM device drivers, add a couple of fixes to the Ceph and FUSE filesystems, as well as update the networking stack with B.A.T.M.A.N. Advanced and CAN changes.
Many GNU/Linux distributions are still using kernel packages from the Linux 4.8 and 4.4 LTS series, despite the fact that Linux kernel 4.9 is out, so you should update your system to Linux kernel 4.4.39 LTS and/or Linux kernel 4.8.15 as soon as they land in the stable software repositories of your favorite distro, or upgrade directly to Linux kernel 4.9, which might just be the next LTS (Long Term Support) branch. Either way, you can download these new builds right now from kernel.org.
