Why not all stable branches? You do not want to move from 4.9.y to 4.14.y and have a regression, right? What about 4.4.y? > Why this patch is needed: Due to a request to handle CVE-2017-17741, we would need to backport this patch to our kernel. The patch is already in mainline:https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e39d200fa5bf5b94a0948db0dae44c1b73b84a56 What is "our kernel"? > Could you please include this patch in 4.9.y stable tree branch? Have you looked at the recent 4.9-rc release already and tested it out to see if it works properly for you for this issue? thanks, greg k-h
