+Subject: [PATCH] include sys/sysmacros.h for major/minor
+
+These functions are not part of any official spec, and glibc has always
+kept them in sys/sysmacros.h.  As glibc moves to conform to POSIX, and
+more alternative C libraries come up, we need to include this header
+explicitly to get the prototypes.  Otherwise we fail to build like:
+
+affinity.c: In function 'affinity_file':
