    I was looking in this area too and was thinking of a way to consolidate the
    creation of RT/DL tasks in the kernel and the way we set the priority.

    Does it make sense to create a new header for RT priorities for kthreads
    created in the kernel so that we can easily track and rationale about the
    relative priorities of in-kernel RT tasks?

    When working in the FW world such a header helped a lot in understanding what
    runs at each priority level and how to reason about what priority level makes
    sense for a new item. It could be a nice single point of reference; even for
    admins.

    Cheers
