Modified files:
sys/kern sched_ule.c
Log:
- Allow static_boost to specify no boost with '0', traditional kernel
fixed pri boost with '1' or any priority less than the current thread's
priority with a value greater than two. Default the boost to
PRI_MIN_TIMESHARE to prevent regular user-space threads from starving
threads in the kernel. This prevents these user-threads from also
being scheduled as if they are high fixed-priority kernel threads.
- Restore the setting of lowpri in tdq_choose(). It has to be either here
or in sched_switch(). I accidentally removed it from both places.
