* A directory entry has a struct dirent at the front of it, containing its
* inode number, the length of the entry, and the length of the name
* contained in the entry.  These are followed by the name padded to a 4
* byte boundary with null bytes.  All names are guaranteed null terminated.
* The maximum length of a name in a directory is MAXNAMLEN.
