Making It Mount-able

To make the file-system mountable, we implement the "stamfs_read_super()" function:

• Read the super-block from the hard-disk.
• Verify the STAMFS signature is there.
• Initialize the "struct super_block" we got.
• Initialize a "struct stamfs_super_meta" and attach as the super-block's FS private data.
• Load the root inode (see next slide), and put in the dcache.
