FYI, I did a quick test for other recent updated linux-stable-rc tree, it seems we also backport kaiser patch to 3.2.y and 3.16.y tree (but not 3.18.y tree, why?), 3.2.y and 3.16.y has same issue, to fix it, these 2 branches also need this patch. (it can clean apply). They also need another earlier patch which has been merged to 4.4/4.9: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/commit/?h=linux-4.4.y&id=b33c3c64c4786cd724ccde6fa97c87ada49f6a73 On Sat, Jan 13, 2018 at 6:51 AM, Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> wrote: > On Fri, Jan 12, 2018 at 03:05:10PM -0800, lepton wrote: >> FYI, this patch also clean applied to 4.9.y tree.
