+Subject: cifs: fix missed refcounting of ipc tcon
+
+From: Paulo Alcantara <pc@cjr.nz>
+
+commit 65de262a209da0951eb9bc60b3b7faf3bbffa38a upstream.
+
+Fix missed refcounting of IPC tcon used for getting domain-based DFS
+root referrals.  We want to keep it alive as long as mount is active
+and can be refreshed.  For standalone DFS root referrals it wouldn't
+be a problem as the client ends up having an IPC tcon for both mount
+and cache.
+
+Fixes: c88f7dcd6d64 ("cifs: support nested dfs links over reconnect")
