Alan Cox 7ef6ba5d27 Push down the responsibility for zeroing a physical page from the ... caller to vm_page_grab(). Although this gives VM_ALLOC_ZERO a different meaning for vm_page_grab() than for vm_page_alloc(), I feel such change is necessary to accomplish other goals. Specifically, I want to make the PG_ZERO flag immutable between the time it is allocated by vm_page_alloc() and freed by vm_page_free() or vm_page_free_zero() to avoid locking overheads. Once we gave up on the ability to automatically recognize a zeroed page upon entry to vm_page_free(), the ability to mutate the PG_ZERO flag became useless. Instead, I would like to say that "Once a page becomes valid, its PG_ZERO flag must be ignored."		2004-04-24 20:53:55 +00:00
