From c6c4ccd7f96993e106dfea7ef18127f972f2db5e Mon Sep 17 00:00:00 2001 From: Taehee Yoo Date: Sun, 22 Dec 2019 11:26:27 +0000 Subject: hsr: add hsr root debugfs directory In current hsr code, when hsr interface is created, it creates debugfs directory /sys/kernel/debug/. If there is same directory or file name in there, it fails. In order to reduce possibility of failure of creation of debugfs, this patch adds root directory. Test commands: ip link add dummy0 type dummy ip link add dummy1 type dummy ip link add hsr0 type hsr slave1 dummy0 slave2 dummy1 Before this patch: /sys/kernel/debug/hsr0/node_table After this patch: /sys/kernel/debug/hsr/hsr0/node_table Signed-off-by: Taehee Yoo Signed-off-by: David S.
