Modified Files:
src/sys/uvm: uvm_pglist.c
Log Message:
Counter tweaks:
- Don't need to count anonpages+filepages any more; clean+unknown+dirty for
each kind of page can be summed to get the totals.
- Track the number of free pages with a counter so that it's one less thing
for the allocator to do, which opens up further options there.
- Remove cpu_count_sync_one(). It has no users and doesn't save a whole lot.
For the cheap option, give cpu_count_sync() a boolean parameter indicating
that a cached value is okay, and rate limit the updates for cached values
to hz.
