From kernel v3.0 to v3.8, MAX_RT_PRIO is defined in linux/sched.h.
From kernel v3.9 to v3.14, MAX_RT_PRIO is defined in linux/sched/rt.h,
which is not included by linux/sched.h (hence this work-around).
From kernel v3.15 onwards, MAX_RT_PRIO is defined in linux/sched/prio.h,
which is included by linux/sched.h.
Add the missing linux/sched/rt.h include for the affected kernel version
range.
