A rule for stable tree is patch should go into mainline kernel firstly, then go into stable. This patch is in md development tree, I guess it will still take some time for it going into 4.12 stable tree. So is it Okey for me to submit this patch into stable branch of openSUSE kernel ? >From your answer, I feel you would mean: fix it now. > > 2) I guess it should be in stable branch of openSUSE tree on > > https://github.com/openSUSE/kernel-source/tree/stable, am I right ? > > Yes. > > The kernel git tree is shared by both SUSE and openSUSE, BTW.
