[Xen-devel] SetPageForeign in netback

["Zang Hongyong" <zanghongyong@xxxxxxxxxx>]

hi,
  in netback init mmap_pages, 
                SetPageForeign(page, netif_page_release);
  that is, page->index = netif_page_release
  while netif_page_release is a function.

  so what's the meaning of SetPageForeign? 
  And when the function  netif_page_release() will be called?

thanks in advance.
