H A D | vm_radix.h | diff 226930 Sun Oct 30 11:23:25 MDT 2011 jeff - Support two types of nodes, red and black, within the same radix tree. Black nodes support standard active pages and red nodes support cached pages. Red nodes may be removed without the object lock but will not collapse unused tree nodes. Red nodes may not be directly inserted, instead a new function is supplied to convert between black and red. - Handle cached pages and active pages in the same loop in vm_object_split, vm_object_backing_scan, and vm_object_terminate. - Retire the splay page handling as the ifdefs are too difficult to maintain. - Slightly optimize the vm_radix_lookupn() function. |
