Before this commit u2mfn got the address via kmap(get_user_pages(...)). This has the problem that get_user_pages() does not work in some cases. For example when qemu in a stubdom tries to get the mfn for a page which is mapped from the target domain u2mfn fails because get_user_pages() cannot be used for such mappings. So get the address from the pte with apply_to_page_range(). Since we are only interested in one page get_locked_pte() would be simpler but it's not available to modules. |
