Linus Torvalds Announces Release of Linux 3.9

Following what Linus Torvalds called a "very quiet" week, the Finnish American open-source software guru officially released the Linux 3.9 kernel. The latest kernel had been in development for 10 weeks and includes a device mapper target that allows a user to configure a solid state drive (SSD) as a cache for hard disk drives (HDDs) to increase system performance.

The release comes a week later than Torvalds would have liked, though he seemed more concerned with people trying to "game the system" than with the slight delay.

"So the last week was much quieter than the preceding ones, which makes me suspect that one reason -rc7 was bigger than I liked was that people were gaming the system and had timed some of their pull requests for just before the release, explaining why -rc7 was big enough that I didn't actually want to do a final release last week. Please don't do that," Torvalds stated in his official announcement.

There's quite a bit that's new and/or improved in Linux 3.9, including improved support for the F2FS (Flash Friendly File System) file system for Samsung developers, improved ARM support, a Zero-Power optical device driver, audio and sound improvements, initial support for AMD Radeon HD 8000 Series graphics cards, better power management, faster LZO compression, experimental RAID 5/6 support for the Btrfs file system, and more.
