Just a small correction: dir_lookup will treat "" like ".".  The problem 
is with dir_{link,unlink,mkdir,rmdir,rename} which receive the last 
pathname component of the referred pathname.  When this pathname 
component is "", these functions use diskfs_lookup and return EINVAL.

What POSIX requires precisely is ENOENT when the whole pathname is empty 
string: http://mail.gnu.org/archive/html/bug-hurd/2004-04/msg00252.html
