Subject: SUNRPC: Introduce support for setting the port number in IPv6 addresses
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=20612005c51a5ba1bb17902276b9216825958724;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

SUNRPC: Introduce support for setting the port number in IPv6 addresses

We could clone xs_set_port, but this is easier overall.
