-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'
