From d68a90e148f5a82aa67654c5012071e31c0e4baa Mon Sep 17 00:00:00 2001 From: Max Gurtuvoy Date: Tue, 19 Jun 2018 15:45:33 +0300 Subject: [PATCH] nvmet: reset keep alive timer in controller enable 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.
