(1) Removing MAX_USER_RT_PRIO was already discussed here in April 2020:
https://lkml.kernel.org/r/20200423094403.6f1d2b8d@gandalf.local.home
(2) USER_PRIO() and related macros are not used anymore except in one case for powerpc where MAX_USER_PRIO can be replaced by NICE_WIDTH. Set_load_weight(), task_prio(), cpu_weight_nice_write_s64(), __update_max_tr() don't use USER_PRIO() but priority - MAX_RT_PRIO.
(3) The function header of task_prio() needs an update. It looks ancient since it mentions a prio space [-16 ... 15] for mormal tasks. I can't figure out why this range is mentioned here? Maybe the influence of the 'sleep-bonus interactivity' feature which was removed by commit f3479f10c5d6 ("sched: remove the sleep-bonus interactivity code")?
