dyson 96/05/28 22:12:25 Modified: sys/vm vm_map.c default_pager.c Log: Make sure that pageout deadlocks cannot occur. There is a problem that the datastructures needed to support the swap pager can take enough space to fully deplete system memory, and cause a deadlock. This change keeps large objects from being filled with dirty pages without the appropriate swap pager datastructures. Right now, default objects greater than 1/4 the size of available system memory are converted to swap objects, thereby eliminating the risk of deadlock.
