markj 4159d33f6b Release laundered vnode pages to the head of the inactive queue. ... The swap pager enqueues laundered pages near the head of the inactive queue to avoid another trip through LRU before reclamation. This change adds support for this behaviour to the vnode pager and makes use of it in UFS and ext2fs. Some ioflag handling is consolidated into a common subroutine so that this support can be easily extended to other filesystems which make use of the buffer cache. No changes are needed for ZFS since its putpages routine always undirties the pages before returning, and the laundry thread requeues the pages appropriately in this case.
