What is the linux kernel ?

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.

New in version Linux Kernel 3.18 :

• It's been a quiet week, and the patch from rc7 is tiny, so 3.18 is out.
• I'd love to say that we've figured out the problem that plagues 3.17 for a couple of people, but we haven't. At the same time, there's absolutely no point in having everybody else twiddling their thumbs when a couple of people are actively trying to bisect an older issue, so holding up the release just didn't make sense. Especially since
• that would just have then held things up entirely over the holiday break.
• So the merge window for 3.19 is open, and DaveJ will hopefully get his bisection done (or at least narrow things down sufficiently that we have that "Ahaa" moment) over the next week. But in solidarity with Dave (and to make my life easier too ;) let's try to avoid introducing any _new_ nasty issues, ok?
