struct VmoBacklink
Defined at line 183 of file ../../zircon/kernel/vm/include/vm/page_queues.h
Used to represent and return page backlink information acquired whilst holding the page queue
lock. As a VMO may not destruct while it has pages in it, the cow RefPtr will always be valid,
although the page and offset contained here are not synchronized and must be separately
validated before use. This can be done by acquiring the returned vmo's lock and then validating
that the page is still contained at the offset.
