From acdff0df54264d187b648b80bc18265f0698f1ad Mon Sep 17 00:00:00 2001 From: Jianlin Lv Date: Sun, 14 Mar 2021 22:56:29 +0800 Subject: [PATCH] bonding: Added -ENODEV interpret for slaves option When the incorrect interface name is stored in the slaves/active_slave option of the bonding sysfs, the kernel does not record the log that interface does not exist. This patch adds a log for -ENODEV error, which will facilitate users to figure out such issue. Signed-off-by: Jianlin Lv Signed-off-by: David S.
