Given that any "new" android device that gets shipped "soon" should be using 4.9.y or newer, is this a real issue? And if it is, I'm sure that asking for those patches to be backported to 4.4.y would be just fine, have you asked? Note that I know of Android Go devices, running 3.18.y kernels, do NOT use the in-kernel memory killer, but instead use the userspace solution today. So trying to get another in-kernel memory killer solution added anywhere seems quite odd. thanks, greg k-h
