Subject: [PATCH 3.18 26/69] afs: Fix missing put_page()

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Howells <dhowells@...hat.com>


[ Upstream commit 29c8bbbd6e21daa0997d1c3ee886b897ee7ad652 ]

In afs_writepages_region(), inside the loop where we find dirty pages to
deal with, one of the if-statements is missing a put_page().
