Because as soon as fstatvfs is fixed (for some combination of
kernel/filesystem/libc), you are wrong again. The f_blocks, f_bfree and
other fields are supposed to be counted as f_frsize sized blocks. And at
least for nfs, f_frsize does not always equal f_bsize.
So if you use fstatvfs, you must use f_frsize. If that is broken you
must revert to fstatfs.
