PCPU_LAZY_INC() which increments elements in it for cases where we can afford the occassional inaccuracy. Use of per-cpu stats counters avoids significant cache stalls in various critical paths that would otherwise severely limit our cpu scaleability. Adjust all sysctl's accessing cnt.* elements to now use a procedure which aggregates the requested field for all cpus and for the global vmmeter. The global vmmeter is retained, since some stats counters, like v_free_min, cannot be made per-cpu. Also, this allows us to convert counters from the global vmmeter to the per-cpu vmmeter in a piecemeal fashion, so have at it! |
