From 1ff8038988adecfde71d82c0597727fc239d4e8c Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 12 Dec 2005 16:24:33 -0800 Subject: [PATCH] get_user_pages: don't try to follow PFNMAP pages Nick Piggin points out that a few drivers play games with VM_IO (why? who knows..) and thus a pfn-remapped area may not have that bit set even if remap_pfn_range() set it originally. So make it explicit in get_user_pages() that we don't follow VM_PFNMAP pages, since pretty much by definition they do not have a "struct page" associated with them.
