Anyone Wants Some Homework?

• Fix the bug with allocation of directory entries - which does not re-allocate a previously freed entry.
• Allow creating larger files/directories, by having the last entry in an inode's block index, point to another block containing index data.
• Support a larger free blocks list in a similar manner (note: This is trickier - where do we store the blocks comprising the free blocks list?).
• Support having more inodes, in a similar manner.
• Add support for 'rename'.
• Add support for variable-length file names.
• Re-implement directories handling to use the page cache, rather then using buffer-heads directly.
