From 3c140d22e3c2b7992abfd4c8db6411669ecc1ab7 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 11 Mar 2020 15:29:25 +0900 Subject: [PATCH] net: drop_monitor: use IS_REACHABLE() to guard net_dm_hw_report() [ Upstream commit 1cd9b3abf5332102d4d967555e7ed861a75094bf ] In net/Kconfig, NET_DEVLINK implies NET_DROP_MONITOR. The original behavior of the 'imply' keyword prevents NET_DROP_MONITOR from being 'm' when NET_DEVLINK=y. With the planned Kconfig change that relaxes the 'imply', the combination of NET_DEVLINK=y and NET_DROP_MONITOR=m would be allowed. Use IS_REACHABLE() to avoid the vmlinux link error for this case.
