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.


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.

What's new in Linux Kernel 4.0 RC2:

• It's been a very quiet week, for being this early in the release process. Sure, 3.19-rc2 was even smaller, so it continues a trend, but that was the xmas week. I hope this low volume is just because the 4.0 merge window itself was somewhat calmer than most recent releases. But I suspect the real reason is that the driver and networking trees from GregKH and davem are pending, and didn't make rc2.
