Modified Files:
src/sys/kern: kern_synch.c
src/sys/sys: sched.h
src/sys/uvm: uvm_extern.h uvm_glue.c uvm_meter.c
Log Message:
- Merge sched_pstats() and uvm_meter()/uvm_loadav(). Avoids double loop
through all LWPs and duplicate locking overhead.
- Move sched_pstats() from soft-interrupt context to process 0 main loop.
Avoids blocking effect on real-time threads. Mostly fixes PR/38792.
Note: it might be worth to move the loop above PRI_PGDAEMON. Also,
sched_pstats() might be cleaned-up slightly.
