Linus Torvalds has released Linux kernel 3.9. The latest version of the kernel now has a device mapper target which allows a user to setup an SSD as a cache for hard disks to boost disk performance under load. There's also kernel support for multiple processes waiting for requests on the same port, a feature which will allow it to distribute server work better across multiple CPU cores.

KVM virtualisation is now available on ARM processors and RAID 5 and 6 support has been added to Btrfs's existing RAID 0 and 1 handling. Linux 3.9 also has a number of new and improved drivers which means the kernel now supports the graphics cores in AMD's next generation of APUs and also works with the high-speed 802.11ac Wi-Fi chips which will likely appear in Intel's next mobile platform.

An overview of these and the many other new features in version 3.9 of the Linux kernel, along with a look at the new features expected in 3.10, is provided in a Kernel Log special:

For those who want a detailed breakdown of the innovations and features, the three part Kernel Log mini-series, Coming in 3.9, provides more information:
