[PATCH] mm/page-writeback: export account_page_dirtied()

[Yehuda Sadeh]

The ceph filesystem implementation of set_page_dirty is based on
__set_page_dirty_nobuffers(), and needs to use account_page_dirtied(). It
uses its own implementation as it needs to set the page private bit and
value under the tree lock. This exports it using EXPORT_SYMBOL_GPL.
