This weekend was the release of Linux 4.9-rc1 to mark the end of the 4.9 kernel merge window. As such, here’s our usual feature overview recapping all of the changes to Linux 4.9 that have us excited about the next version of this open-source kernel.
Some of the highlights include AMDGPU GCN 1.0 experimental support, memory protection keys support, mainline support for the LG Nexus 5 and Raspberry Pi Zero (along with a lot of other ARM hardware), the Greybus subsystem was added, support for vmapped stacks, and many other additions.
