"later" kernels are hundreds of thousands of changes newer than the
kernel you are using, so really, the responsibility is for you to try it
out on your workload to see if it works better or not (and if not, then
let the developers know, after you have tried 4.13). There is nothing
we can do to go back in time and change an obsolete, old, kernel version
:)
good luck!
