From fc5e58c0c4fd86881ec8ba8e46e41a07e25dc7a6 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Thu, 24 Mar 2011 16:14:26 +0200 Subject: [PATCH] UBIFS: use GFP_NOFS properly This patch fixes a brown-paperbag bug which was introduced by me: I used incorrect "GFP_KERNEL | GFP_NOFS" allocation flags to make sure my allocations do not cause write-back. But the correct form is "GFP_NOFS".
