Homework 4

1. Read file Documentation/CodingStyle in your linux kernel source tree, then list 3 aspects of the Linux coding style that you normally follow in your C programming, and 3 that you don't (if you normally use the Linux coding style in your programming, select the 3 that you think you follow the least).
2. Read about the CP/M operating system at wikipedia. To get credit for this question, name the three main layers of the operating system, with a one-line description for each.
3. Tanenbaum, p. 264, exercise 4-10. Be sure to answer both parts of the question -- give an expression, and explain how realistic this amount is.
4. Tanenbaum, p. 450, exercise 6-17, modified as follows. Each block on disk is 1024 bytes, not 1024KB. The inode contains 10 addresses (block pointers), of which the last one is an indirect pointer to a block of 1024 bytes containing pointers to blocks. Each block pointer requires 4 bytes to store. What is the maximum file size?
5. Tanenbaum, p. 450, exercise 6-18, modified as follows. The inode contains 10 addresses (block pointers), and again each pointer to a block is 4 bytes.
6. Tanenbaum, p. 759, exercise 10-16.
