Large (> 1 TiB) UDF filesystems appear subject to several problems when
mounted on 64-bit systems:
* readdir() can fail on a directory containing File Identifiers residing
above 0x7FFFFFFF. This manifests as a 'ls' command failing with EIO.
* FIBMAP on a file block located above 0x7FFFFFFF can return a negative
value. The low 32 bits are correct, but applications that don't mask the
high 32 bits of the result can perform incorrectly.
* Unsigned values > 0x7FFFFFFF are output as negative numbers in some
driver printks, e.g.:
Partition (0 type 1511) starts at physical 460, block length -1779968542
Take care to use "%u" when printing unsigned values and to use unsigned
types to store UDF block addresses.
