| Subject: [PATCH] cifs: log warning message (once) if out of disk space |
| |
| commit d6fd41905ec577851734623fb905b1763801f5ef upstream. |
| |
| We ran into a confusing problem where an application wasn't checking |
| return code on close and so user didn't realize that the application |
| ran out of disk space. log a warning message (once) in these |
| cases. For example: |
| |
| [ 8407.391909] Out of space writing to \\oleg-server\small-share |
