Greetings, I was wondering what is the guideline in regards to which kernels are supported by OpenStack in the various Linux distributions.
Looking at [1], Taking for example latest CentOS major (7): Every "minor" version is released with a different kernel version, the oldest being released in 2014 (CentOS 7.0, kernel 3.10.0-123) and the newest released in 2018 (CentOS 7.6, kernel 3.10.0-957)
While I understand that OpenStack projects are expected to support all CentOS 7.x releases. Does the same applies for the kernels they originally came out with?
The reason I'm asking, is because I was working on doing some cleanup in neutron [2] for a workaround introduced because of an old kernel bug, It is unclear to me if it is safe to introduce this change.
