No. With DRBD10 we will give up RHEL6 kernels. From a quick look at the
build matrix, RHEL7 then has the oldest kernel we will support.

All in all the build magic/compat, especially for HEAD (which is the dev
branch for 10; there is also a stable one for 9.0.X) needs some love.

So yeah, thanks, but for now play with something else, it will make you
happier :D
