| 2 | Subject: zfcp: Cancel WKA port work on adapter dequeue | |
| 3 | References: bnc#518291,LTC#54988 | |
| 4 | ||
| 5 | Symptom: Oops when enabling / disabling lots of FCP subchannels | |
| 6 | while setting the chpid off / on. | |
| 7 | Problem: The delayed_work for the directory server wka port is | |
| 8 | being executed after the adapter struct has been removed. | |
| 9 | Solution: Before removing the adapter struct make sure that the | |
| 10 | delayed_work is not running. | |
