From a649fd9271773dd0f78e2b9f347bcceecb8827f9 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Tue, 17 Oct 2006 00:09:36 -0700 Subject: [PATCH] invalidate: remove_mapping() fix If remove_mapping() failed to remove the page from its mapping, don't go and mark it not uptodate! Makes kernel go dead. (Actually, I don't think the ClearPageUptodate is needed there at all). Says Nick Piggin: "Right, it isn't needed because at this point the page is guaranteed by remove_mapping to have no references (except us) and cannot pick up any new ones because it is removed from pagecache. We can delete it."
