From: WANG Cong Date: Sat, 11 Jan 2014 00:09:45 +0000 (-0800) Subject: ipv4: register igmp_notifier even when !CONFIG_PROC_FS X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=72c1d3bdd5bf10a789608336ba0d61f1e44e4350;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ipv4: register igmp_notifier even when !CONFIG_PROC_FS We still need this notifier even when we don't config PROC_FS. It should be rare to have a kernel without PROC_FS, so just for completeness. Cc: Stephen Hemminger Cc: David S. Miller Cc: Patrick McHardy Signed-off-by: Cong Wang Signed-off-by: David S.
