void Push (vm_page_t * page)

Add a page to the batch set. Automatically calls |Flush| if the limit is reached.

void PushContent (VmPageOrMarker * page_or_marker)

Removes any content from the supplied |page_or_marker| and either calls |Push| or otherwise

frees it. Always leaves the |page_or_marker| in the empty state.

Automatically calls |Flush| if the limit on pages is reached.

void Flush ()

Performs |Remove| on any pending pages. This allows you to know that all pages are in the

original list so that you can do operations on the list.

Defined at line 309 of file ../../zircon/kernel/vm/vm_cow_pages.cc

size_t freed_count ()

Returns the number of pages that were added to |freed_list_| by calls to Flush(). The

|freed_count_| counter keeps a running count of freed pages as they are removed and added to

|freed_list_|, avoiding having to walk |freed_list_| to compute its length.
