| H A D | vm_meter.c | diff 244043 Sat Dec 08 22:40:04 MST 2012 alc In the past four years, we've added two new vm object types. Each time, similar changes had to be made in various places throughout the machine- independent virtual memory layer to support the new vm object type. However, in most of these places, it's actually not the type of the vm object that matters to us but instead certain attributes of its pages. For example, OBJT_DEVICE, OBJT_MGTDEVICE, and OBJT_SG objects contain fictitious pages. In other words, in most of these places, we were testing the vm object's type to determine if it contained fictitious (or unmanaged) pages. To both simplify the code in these places and make the addition of future vm object types easier, this change introduces two new vm object flags that describe attributes of the vm object's pages, specifically, whether they are fictitious or unmanaged.
