[Xen-devel] question on get_page_and_type()
Could someone please explain the following
What is the purpose of get_page_and_type(page, domain, PGT_writable_page) and why is it needed when doing a grant copy in __gnttab_copy()?
Why can't we just use get_page() to prevent the page from being freed while we are doing the copy?
