The patch with the fallback to FileFsSizeInformation works as expected.

The FileFsFullSizeInformation path still fails with the same error code even
with these changes (I've added a few debug_printf to show the results even
in the case of success):

   31 3473313 [main] df 28752 statvfs: (/home/gratz, 0x28A864),
file_attributes 48
 1186 3474499 [main] df 28752 fhandler_disk_file::fstatvfs: 0xC000000D =
NtQueryVolumeInformationFile(\??\H:\GNU, FileFsFullSizeInformation)
  479 3474978 [main] df 28752 fhandler_disk_file::fstatvfs: 0x0 =
NtQueryVolumeInformationFile(\??\H:\GNU, FileFsSizeInformation)
 1709 3476687 [main] df 28752 fhandler_disk_file::fstatvfs: 0 =
fstatvfs(/home/gratz, 0x28A864)
   34 3476721 [main] df 28752 statvfs: 0 = statvfs(/home/gratz,0x28A864)
