Nevertheless, it is quite possible that real-world use will result in
     some situation requiring that high-stress workloads run on hardware
     not designed to accommodate them, and also requiring that the kernel
     refrain from marking clocksources unstable.
     
     Therefore, provide an out-of-tree patch that reacts to this situation

out-of-tree means it will not be submitted?


I think it would make sense upstream, but perhaps guarded with some option.
