Modified files:
sys/kern kern_fork.c kern_proc.c sched_ule.c
sched_4bsd.c
sys/sys proc.h
Log:
- Redefine p_swtime and td_slptime as p_swtick and td_slptick. This
changes the units from seconds to the value of 'ticks' when swapped
in/out. ULE does not have a periodic timer that scans all threads in
the system and as such maintaining a per-second counter is difficult.
- Change computations requiring the unit in seconds to subtract ticks
and divide by hz. This does make the wraparound condition hz times
more frequent but this is still in the range of several months to
years and the adverse effects are minimal.
