-Subject: [PATCH] add additional uapi guards for Linux kernel header files
-
-With Linux kernel 4.16 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
-it possible to compile source files which include both the libc
-headers and the kernel userspace headers.
-
-This extends the definitions done in commit 04983f227238 ("make
-netinet/in.h suppress clashing definitions from kernel headers")
