We have no idea what patches will go into the default CentOS kernels ..
we rebuild the source code that Red Hat releases for RHEL.

We do maintain several kernels on our own ..

1.  CentOS Plus kernel .. We add patches there, but it would need to be
backported if it does not apply.  We use this bug to maintain the Plus
Kernel:

https://bugs.centos.org/view.php?id=6828

2. Kernel in the AltArch tree .. We have to use a different kernel for
armhfp, and we also build it for other CentOS arches .. it lives at:

http://mirror.centos.org/altarch/7/kernel/

This kernel is based on a kernel.org LTS kernel (currently 4.14.x) and
if that patch gets rolled into the LTS stream, it will be in our kernels
there.

3. Experimential kernel in the AltArch tree .. this is a newer LTS
kernel (which we will use in future armhfp releases .. it is currently
based on 4.19.x LTS kernel.org kernel.  This one will replace the 4.14
kernel in the 7.7.x release whenever that happens.  If that patch makes
it into 4.19.x LTS at kernel.org then it will be in this kernel too.
