From: William Manley Date: Tue, 6 Aug 2013 18:03:14 +0000 (+0100) Subject: net: igmp: Don't flush routing cache when force_igmp_version is modified X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5c6fe01c1fe3140a8fb088d2a9c32548b731c35e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git net: igmp: Don't flush routing cache when force_igmp_version is modified The procfs knob /proc/sys/net/ipv4/conf/*/force_igmp_version allows the IGMP protocol version to use to be explicitly set. As a side effect this caused the routing cache to be flushed as it was declared as a DEVINET_SYSCTL_FLUSHING_ENTRY. Flushing is unnecessary and this patch makes it so flushing does not occur. Requested by Hannes Frederic Sowa as he was reviewing other patches adding procfs entries.
