Linux 3.4 Kernel Gets Btr, BATMAN

Among the other new features in Linux 3.4 is a set of improvements to B.A.T.M.A.N. BATMAN, or Better Approach To Mobile Adhoc Networking, first landed in the 2.6.38 Linux kernel back in March of 2011. In the 3.4 kernel, B.A.T.M.A.N has been improved to now have the ability to alter the routing algorithm used to create the ad hoc mesh network.

KVM virtualization also gets a big boost in Linux 3.4. New kernel features contributed by Red Hat expand the maximum number of virtual CPUs (vCPUs) that can be supported in Linux, from 64 all the way to 160.
