Konstantin Belousov 48cc2fc774 Drop page queues mutex on each iteration of vm_pageout_scan over the ... inactive queue, unless busy page is found. Dropping the mutex often should allow the other lock acquires to proceed without waiting for whole inactive scan to finish. On machines with lot of physical memory scan often need to iterate a lot before it finishes or finds a page which requires laundring, causing high latency for other lock waiters.
