Hi,

The LINUX_VERSION_CODE is fixed since 4.9.255, see here:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=42efb098c75f9d4b95f7cf35d3d52e80cc2fde82

SUBLEVEL should still contains the minor kernel version number.

We could extend the macros in backport/backport-include/linux/version.h 
to check for SUBLEVEL manually if it overflows.
