Subject: net: ping: make ping_v6_sendmsg static
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6579a023a881e0592ce9a98fdfcbcc0a2a096aa7;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

net: ping: make ping_v6_sendmsg static

As ping_v6_sendmsg is used only in this file,
making it static

The body of "pingv6_prot" and "pingv6_protosw" were
moved at the middle of the file, to avoid having to
declare some static prototypes.
