Subject: [ 11/24] ceph: fix dentry reference leak in encode_fh()

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

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

From: David Zafman <david.zafman@...tank.com>

commit 52eb5a900a9863a8b77a895f770e5d825c8e02c6 upstream.

Call to d_find_alias() needs a corresponding dput()

This fixes http://tracker.newdream.net/issues/3271
