Chapter 2 concern system calls. IMHO, this should be maintained by kernel developpers and updated each time I update the kernel so that it is always in sync. I would like to understand what is the contract the developper has implemented. The limitations of a system call are the developpers regrets and their plans for future evolutiond. I do not care if the style is not good. What I care is how it should be used.
