Subject: [PATCH -next] fs: fix fs/fs-writeback.c build error

From: Randy Dunlap <[email-masked]>
Date: Thu, 05 Jan 2012 16:18:30 -0800

From: Randy Dunlap <[email-masked]>

In linux-next, fs/fs-writeback.c no longer #includes <linux/buffer_head.h>,
which #included <linux/pagemap.h>, so add that latter header file to
<linux/writeback.h> to fix the build error:

fs/fs-writeback.c:510:11: error: 'PAGE_CACHE_SHIFT' undeclared (first use in this function)
