Just wanted to make a note on the centosplus kernel.

While the distro kernel is a strict rebuild of the RHEL kernel, CentOS
also provides a custom kernel (called kernel-plus in C7 and C8). It
can freely accommodate bug fixes (patches) and added features.

For example, you can see the actual patches for CentOS-7 here:


A request for a new patch/feature can be filed at
http://bugs.centos.org for consideration.
