From e154cb7b0ab961f9d785ed34c2d7128413e7083d Mon Sep 17 00:00:00 2001 From: Shyam Prasad N Date: Sun, 16 Jan 2022 11:19:36 +0000 Subject: cifs: fix the cifs_reconnect path for DFS Recently, the cifs_reconnect code was refactored into two branches for regular vs dfs codepath. Some of my recent changes were missing in the dfs path, namely the code to enable periodic DNS query, and a missing lock.
