Which file should you patch? How do I apply the patch?

first you must download the source code of the linux kernel. the patch is applied in the root directory of the linux kernel source, before compiling. please google how to apply patches to the linux kernel using your distro of choice. this thread should be for information pertinent to the patch, not generic questions about the linux kernel itself.

Could this be applied with kpatch/live patching?
