From 65de262a209da0951eb9bc60b3b7faf3bbffa38a Mon Sep 17 00:00:00 2001 From: Paulo Alcantara Date: Thu, 2 Dec 2021 15:29:35 -0300 Subject: cifs: fix missed refcounting of ipc tcon 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.
