Subject: tcp: Like icmp use register_pernet_subsys
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6a1b3054d9fd98001a6631501caf1969138ee00d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

tcp: Like icmp use register_pernet_subsys

To remove the possibility of packets flying around when network
devices are being cleaned up use reisger_pernet_subsys instead of
register_pernet_device.
