Subject: [PATCH v2] Fix a build error when BLOCK=n

mm/filemap.c: In function '__filemap_fdatawrite_range':
mm/filemap.c:200: error: implicit declaration of function 'mapping_cap_writeback_dirty'

This happens when we don't use/have any block devices and a NFS root filesystem
is used

mapping_cap_writeback_dirty() is defined in linux/backing-dev.h which used to be
provided in mm/filemap.c by linux/blkdev.h until commit
f5ff8422bbdd59f8c1f699df248e1b7a11073027
