Deleting Inodes From Disk

Deleting inodes from disk is done using the super-block's delete_inode operation, and the stamfs_delete_inode() function:

• Sanity check - make sure this is not a "bad inode" (i.e. an invalid inode).
• Set the inode's size field to zero, and if it contains any data blocks - invoke stamfs_inode_truncate() (see below).
• Finally, free the inode, using stamfs_inode_free_ino() (which merely frees the inode number, the inodes block and its block index block).
