Subject: linux-next: build failure after merge of the btrfs-kdave tree

Hi David,

After merging the btrfs-kdave tree, today's linux-next build (x86_64
allmodconfig) failed like this:

fs/ntfs/attrib.c: In function 'ntfs_attr_set':
fs/ntfs/attrib.c:2549:35: error: implicit declaration of function 'inode_to_bdi' [-Werror=implicit-function-declaration]

Caused by commit

  a685fa61566d ("remove mapping from balance_dirty_pages*()")

I assume some forgotten include(s).

I have used the btrfs-kdave tree from next-20160906 for today.
