Mark Johnston 2913cc4637 vm_pageout: Avoid rounding down the inactive scan target ... With helper page daemon threads, enabled by default in r364786, we divide the inactive target by the number of threads, rounding down, and sum the total number of pages freed by the threads. This sum is compared with the original target, but by rounding down we might lose pages, causing the page daemon control loop to conclude that inactive queue scanning isn't keeping up with demand for free pages. Typically this results in excessive swapping. Fix the problem by accounting for the error in the main pagedaemon thread's target. Note that by default the problem will manifest only in systems with >16 CPUs in a NUMA domain.
