Creating A New Inode

To create a new inode, we have stamfs_inode_new_ino():

• Allocate a block for the inode, and a block for the inode's block index.
• Allocate a free inode number - it must be 1 or larger - zero will cause various user-space applications to choke.
• Allocate a VFS inode struct.
• Set the inode's link-count to 1 (it will be in a directory, which will point to it).
• Set the rest of the inode struct's fields.
• Attach STAMFS's meta-data to the inode's private data.
• Set the various VFS operations (inode-operations, file-operations, address-space operations) based on the inode's type (dir, file...).
• Add the inode to the parent directory.
