From: Jo-Philipp Wich Date: Wed, 1 Apr 2020 16:19:30 +0000 (+0200) Subject: luci-mod-status: luci-bwc: skip "." and ".." when finding netdevs X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=16f0997bdbf85df0c7bae7f0773a118714d15cdf;p=oweals%2Fluci.git 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.
