It looks like the infrastructure to facilitate live kernel patching will be added to the Linux 3.20 kernel, the result of collaboration for SUSE’s kGraft and Red Hat’s Kpatch.
Last year SUSE and Red Hat introduced their own live kernel patching mechanisms after not knowing each company was independently working on a solution for patching running versions of the Linux kernel against basic security/bug fixes. In the months since the unveiling of kGraft and Kpatch, the kernel developers have been working together to come up with a common base that addresses the needs of each implementation. That common work for supporting Kpatch and kGraft is now what’s ready for merging into Linux 3.20.
