From ba7d16c7794213b591a0ea415d975858d6a7dfd8 Mon Sep 17 00:00:00 2001 From: Eran Ben Elisha Date: Sun, 29 Mar 2020 14:05:54 +0300 Subject: [PATCH] devlink: Implicitly set auto recover flag when registering health reporter When health reporter is registered to devlink, devlink will implicitly set auto recover if and only if the reporter has a recover method. No reason to explicitly get the auto recover flag from the driver. Remove this flag from all drivers that called devlink_health_reporter_create. All existing health reporters set auto recovery to true if they have a recover method. Yet, administrator can unset auto recover via netlink command as prior to this patch.
