| Subject: [PATCH] Set unicode flag on cifs echo request to avoid Mac error |
| |
| commit 26c9cb668c7fbf9830516b75d8bee70b699ed449 upstream. |
| |
| Mac requires the unicode flag to be set for cifs, even for the smb |
| echo request (which doesn't have strings). |
| |
| Without this Mac rejects the periodic echo requests (when mounting |
| with cifs) that we use to check if server is down |
