Subject: [PATCH][7/8] mm: rmap add/remove interface change
Date: Mon, 20 Mar 2006 08:38:19 -0500	[thread overview]
Message-ID: <bc56f2f0603200538s6ab7fb8h@mail.gmail.com> (raw)

Modify rmap add/remove interface to support passing structure vm_area_struct,
for this structure contains necessary info(vma->vm_wire_change),
so not to wire the same page twice (make_pages_wired and page_add_*_rmap).
