+Subject: [PATCH] fibmap: pull in sys/sysmacros.h for major/minor
+
+These funcs are provided by sys/sysmacros.h, so include the header
+directly.  Building with alternative C libraries can fail otherwise
+like so:
+
+fibmap.c: In function 'print_stat':
+fibmap.c:36:32: warning: implicit declaration of function 'major' [-Wimplicit-function-declaration]
+  printf("dev       [%d:%d]\n", major(st->st_dev), minor(st->st_dev));
+                                ^
+fibmap.c:36:51: warning: implicit declaration of function 'minor' [-Wimplicit-function-declaration]
+  printf("dev       [%d:%d]\n", major(st->st_dev), minor(st->st_dev));
+                                                   ^
+fibmap.o: In function 'print_stat':
+tools/fibmap.c:36: undefined reference to 'minor'
+tools/fibmap.c:36: undefined reference to 'major'
+fibmap.o: In function 'stat_bdev':
+tools/fibmap.c:59: undefined reference to 'minor'
+tools/fibmap.c:59: undefined reference to 'major'
