From 57e3a60b23891905733bfea7a1cb78c2377cc524 Mon Sep 17 00:00:00 2001
From: Khem Raj <raj.khem@gmail.com>
Date: Sun, 9 Jul 2017 15:17:29 -0700
Subject: [PATCH] Define in_* structs for non-glibc system libs
These defines and structs are required to be coming from
userspace netinet/in.h, which is being overridden in klibc
however, libc-compat.h from kernel is only written keeping
glibc in mind, and does not provide adequate guards for musl
to infer that these structs should be defined in linux/in.h
