| Subject: nvmet: reset keep alive timer in controller enable |
| |
| From: Max Gurtuvoy <maxg@mellanox.com> |
| |
| [ Upstream commit d68a90e148f5a82aa67654c5012071e31c0e4baa ] |
| |
| Controllers that are not yet enabled should not really enforce keep alive |
| timeouts, but we still want to track a timeout and cleanup in case a host |
| died before it enabled the controller. Hence, simply reset the keep |
| alive timer when the controller is enabled. |
