/* FileIdBothDirectoryInformation is apparently unsupported on
XP when accessing directories on UDF. When trying to use it
so, NtQueryDirectoryFile returns with STATUS_ACCESS_VIOLATION.
It's not clear if the call isn't also unsupported on other
OS/FS combinations. Instead of testing for yet another error
code, let's use FileIdBothDirectoryInformation only on FSes
supporting persistent ACLs, FileBothDirectoryInformation otherwise.

NFS clients hide dangling symlinks from directory queries,
unless you use the FileNamesInformation info class.
