From 16f0997bdbf85df0c7bae7f0773a118714d15cdf Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Wed, 1 Apr 2020 18:19:30 +0200 Subject: [PATCH] luci-mod-status: luci-bwc: skip "." and ".." when finding netdevs Skip the "." and ".." directory entries of "/sys/class/net/" instead of passing them on to libiwinfo's probe function. This avoids a situation where the kernel requests a modprobe of "netdev-." and "netdev-.." over and over again, resulting in high load on lower end systems.
