Subject: kmodloader: modprobe: return 0 for loaded modules
X-Git-Url: https://git.librecmc.org/?p=oweals%2Fubox.git;a=commitdiff_plain;h=21a4bd04062e16164f4f3e1c67005a062f470b0c

kmodloader: modprobe: return 0 for loaded modules

This is the default behaviour with modprobe from kmod package [1] unless
it is explicitly told that the module is to be loaded for --first-time

 [1] http://www.kernel.org/pub/linux/utils/kernel/kmod/

Fixes FS#433
