The addition of Open vSwitch to the mainline Linux kernel is another important addition. Open vSwitch will replace the Linux bridge in the case of more complex switching needs, such as for virtualized server environments. It supports all of the management interface standards, and it's compatible with modern switching chipsets. Being able to change to a different RAID level in Btrfs is an added bonus, and the newly included balancing and debugging tools will keep that operation easy to manage and efficient.
With additional updates to network priority traffic, EFI boot support, memory management, cryptography, and security, the 3.3 kernel is a big deal. It even introduces support for a new hardware architecture, TI C6X from Texas Instruments. If your business runs the cutting edge of Linux hardware and software, this is an upgrade you don't want to miss.
