In the latest glibc, major() and minor() functions are marked as
deprecated (glibc commit dbab6577):
CC util/libvirt_util_la-vircgroup.lo
util/vircgroup.c: In function 'virCgroupGetBlockDevString':
util/vircgroup.c:768:5: error: '__major_from_sys_types' is deprecated:
In the GNU C Library, `major' is defined by <sys/sysmacros.h>.
For historical compatibility, it is currently defined by
<sys/types.h> as well, but we plan to remove this soon.
To use `major', include <sys/sysmacros.h> directly.
If you did not intend to use a system-defined macro `major',
you should #undef it after including <sys/types.h>.
[-Werror=deprecated-declarations]
if (virAsprintf(&ret, "%d:%d ", major(sb.st_rdev), minor(sb.st_rdev)) < 0)
^~

__SYSMACROS_DEFINE_MAJOR (__SYSMACROS_FST_IMPL_TEMPL)
^
Applications are supposed to use gnu_dev_major() or
gnu_dev_minor() respectively.
