/* 64-bit libc uses the kernel's 'struct statfs', accessed via the

statfs() syscall; 32-bit libc uses the kernel's 'struct statfs64'

APIs offered by libc use the kernel shape for their struct statfs

structure; the only difference is that 32-bit programs not

using __USE_FILE_OFFSET64 only see the low 32 bits of some

of the fields (the __fsblkcnt_t and __fsfilcnt_t fields). */
