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'
