Subject: Fix a build error when BLOCK=n
X-Git-Tag: v2.6.24-rc2~103^2~2
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=3a424f2d56613acfb9e583ec9c85a2be3e3af028;p=~emulex%2Finfiniband.git

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 (Fix warnings with
!CONFIG_BLOCK).
