Linux Kernel 3.3 Released With Android Merge, New File Systems & More Security
After a few of rc release, finally Linus Torvalds has released Linux Kernel 3.3. According to the release note by Torvaldas - " Things did indeed calm down during the last week, and the shortlog looks pretty boring. The diffstat from -rc7 is dominated by the arch/tile defconfig changes, the rest is pretty small, although there are changes spread out in various subsystem s(drivers, filesystem, networking, perf tools)."
Summary:- This release features as the most important change the merge of kernel
code from the Android project. But there is more, it also includes support for a new
architecture (TI C6X), much improved balancing and the ability to restripe between
different RAID profiles in Btrfs, and several network improvements: a virtual switch
implementation (Open vSwitch) designed for virtualization scenarios, a faster and
more scalable alternative to the "bonding" driver, a configurable limit to the
transmission queue of the network devices to fight bufferbloat, a network priority
control group and per-cgroup TCP buffer limits. There are also many small
features and new drivers and fixes are also available.
