+Subject: [PATCH] api: fix compatibility of linux/in.h with netinet/in.h
+
+u
+This fixes breakage to iproute2 build with recent kernel headers
+caused by:
+ commit a263653ed798216c0069922d7b5237ca49436007
+ Author: Pablo Neira Ayuso <pablo@netfilter.org>
+ Date: Wed Jun 17 10:28:27 2015 -0500
+
+ netfilter: don't pull include/linux/netfilter.h from netns headers
+
+The issue is that definitions in linux/in.h overlap with those
+in netinet/in.h. This patch solves this by introducing the same
+mechanism as was used to solve the same problem with linux/in6.h

+Subject: [PATCH 1/3] uapi/kernel.h: glibc specific inclusion of sysinfo.h
+
+including sysinfo.h from kernel.h makes no sense whatsoever,
+but removing it breaks glibc's userspace header,
+which includes kernel.h instead of sysinfo.h from their sys/sysinfo.h.
+this seems to be a historical mistake.
+on musl, including any header that uses kernel.h directly or indirectly
+plus sys/sysinfo.h will produce a compile error due to redefinition of
+struct sysinfo from sys/sysinfo.h.
+so for now, only include it on glibc or when including from kernel
+in order not to break their headers.

+Subject: [PATCH 2/3] uapi/libc-compat.h: do not rely on __GLIBC__
+
+Musl provides the same structs as glibc, but does not provide a define to
+allow its detection. Since the absence of __GLIBC__ also can mean that it
+is included from the kernel, change the __GLIBC__ detection to
+!__KERNEL__, which should always be true when included from userspace.
