Just a few questions...

What’s the difference between these two? And what’s the `dirent` argument to
xenhypfs_read_raw() for?
xenhypfs_read() is returning the printable content (if possible),
e.g. "1" for an entry of type integer containing 0x00000001
xenhypfs_read_raw() returns the raw content (e.g. the binary
value 0x00000001 in above example) and the entry format data in
dirent (type, size and enconding of entry).
