+Subject: [PATCH] Add additional uapi guards for Linux kernel header files
+
+With Linux kernel 4.15 it will be possible to guard more parts of the
+Linux header files from a libc. Make use of this in musl to guard all
+the structures and other definitions from the Linux header files which
+are also defined by the header files provided by musl. This will make
+musl compile with the unmodified Linux kernel user space headers.
+
+This extends the definitions done in commit 04983f227238 ("make
+netinet/in.h suppress clashing definitions from kernel headers")
+
+The needed patches were recently accepted for Linux 4.15:
