- It's in the source tree in the uts/{cpu type}/vm directory in a header
- file anon.h. Unless your a source code licensee you probably wont find
- it referenced ...

- BTW) This structure is used for EVERY anonymous virtual page whether this
- page is on swap or actually resident in memory. It's main purpose is to
- hold a reference count of the page so the last reference count on a multiply
- referenced copy-on-write page can actually be tracked ...In particular this
- structure can be used to optimize the copy-on-write fork() ...
