Consider a system where free space is kept in a free-space list.
a. Suppose that the pointer to the free-space list is lost. Can the
system reconstruct the free-space list? Explain your answer.
b. Consider a file system similar to the one used by UNIX with
indexed allocation. How many disk I/O operations might be
required to read the contents of a small local file at /a/b/c?
Assume that none of the disk blocks is currently being cached.
c. Suggest a scheme to ensure that the pointer is never lost as a result
of memory failure.
