Modified Files:
src/sys/kern: kern_event.c
Log Message:
- Rename kqueue_misc_lock -> kqueue_timer_lock, since EVFILT_TIMER is
now its only user. Also initialize it as IPL_SOFTCLOCK; there is no
practical difference in how it operates (it is still an adaptive lock),
but this serves as a visual reminder that we are interlocking against
a callout.
- Add some comments that describe why we don't need to hold kqueue_timer_lock
when detaching an EVFILT_TIMER due to guarantees made by callout_halt().
- Mark timer_filtops as MPSAFE.
