Subject: [PATCH] CIFS: don't log STATUS_NOT_FOUND errors for DFS
Git-commit: 5702591fc6a3f409f460def104ee149330dac82d
Patch-mainline: v4.15-rc4
References: bsc#1051510, bsc#1144333
cifs.ko makes DFS queries regardless of the type of the server and
non-DFS servers are common. This often results in superfluous logging of
non-critical errors.
