For the patches to be picked up in the stable trees, you need to
include CC: <stable@vger.kernel.org> in the sign-off area of the
patches, just cc'ing in the patch posting doesn't help.  See
Documentation/stable_kernel_rules.txt.

Can you submit a v3 with that change, and also add my reviewed-by
line?
