From a94733d0bc630edaedc6ca156752dd5a7cb82521 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 11 Jul 2011 10:47:06 -0400 Subject: Btrfs: use find_or_create_page instead of grab_cache_page grab_cache_page will use mapping_gfp_mask(), which for all inodes is set to GFP_HIGHUSER_MOVABLE. So instead use find_or_create_page in all cases where we need GFP_NOFS so we don't deadlock.
