From: Julius Volz Date: Tue, 2 Sep 2008 13:55:39 +0000 (+0200) Subject: IPVS: Add IPv6 support flag to schedulers X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b14198f6c1bea1687d20723db35d8effecd9d899;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git IPVS: Add IPv6 support flag to schedulers Add 'supports_ipv6' flag to struct ip_vs_scheduler to indicate whether a scheduler supports IPv6. Set the flag to 1 in schedulers that work with IPv6, 0 otherwise. This flag is checked in a later patch while trying to add a service with a specific scheduler. Adjust debug in v6-supporting schedulers to work with both address families.
