With limited fanfare, Linux 4.2 has been released by Linus Torvalds. As usual, it features a large number of new features and fixes, most notably, it includes security module stacking patches, the delay-gradient confestion-control algorithm, improvements to writeback management in control groups, and more. It also includes the addition of he AMDGPU kernel DRM driver to the mainline. Finally, there have been improvements made to processors including support for more ARM devices, cleaned up x86 assembly code, and schedule tweaks and improvements.
