File Systems (20 minutes).

In Lab 4, using a block size of 1024, you created a symbolic link (or soft link) to the name hello-world. Why were you able to store the
content of the symbolic link within the inode itself? Explain why this optimization only works for names less than or equal to 60 bytes.

Regular files are allocated across given a number of blocks. The inode structure records the number of 512 byte blocks used and an
explicit size record. Someone claims that you could just calculate the size using the number of 512 byte blocks. Explain why you need to
explicitly record the size.

The inode (generally) points to the content of a file. Explain the condition(s) required for the kernel to delete an inode and free the blocks
it points to.
