| Subject: smb: client: fix noisy when tree connecting to DFS interlink targets |
| |
| From: Paulo Alcantara <pc@manguebit.com> |
| |
| [ Upstream commit 773dc23ff81838b6f74d7fabba5a441cc6a93982 ] |
| |
| When the client attempts to tree connect to a domain-based DFS |
| namespace from a DFS interlink target, the server will return |
| STATUS_BAD_NETWORK_NAME and the following will appear on dmesg: |
| |
| CIFS: VFS: BAD_NETWORK_NAME: \\dom\dfs |
| |
| Since a DFS share might contain several DFS interlinks and they expire |
| after 10 minutes, the above message might end up being flooded on |
| dmesg when mounting or accessing them. |
| |
| Print this only once per share. |
