From 423bad600443c590f34ed7ce357591f76f48f137 Mon Sep 17 00:00:00 2001 From: Nick Piggin Date: Mon, 28 Apr 2008 02:13:01 -0700 Subject: mm: add vm_insert_mixed vm_insert_mixed will insert either a raw pfn or a refcounted struct page into the page tables, depending on whether vm_normal_page() will return the page or not. With the introduction of the new pte bit, this is now a too tricky for drivers to be doing themselves. filemap_xip uses this in a subsequent patch.
