The 'page' here is not the page addressed by the PTE, but the page *containing* the PTE. (Note that the argument to ptep_to_mm() is a pointer to PTE, not a PTE itself). The page containing the PTEs is allocated either from pte_alloc_map() or pte_alloc_kernel(). page->mapping will be NULL when the page is allocated. It is set to the current task's mm by calling pgtable_add_rmap(). -Ravi. __________________________________ Do you Yahoo!? SBC Yahoo!
