ext4: use __GFP_NOFAIL in ext4_free_blocks() This might be unexpected but pages allocated for sbi->s_buddy_cache are charged to current memory cgroup. So, GFP_NOFS allocation could fail if current task has been killed by OOM or if current memory cgroup has no free memory left. Block allocator cannot handle such failures here yet.
