Question 1: For the project, do I need to perform a study of the whole Linux kernel? Can you provide an example of a Linux subsystem that would be of suitable scope for the project?

Answer to Question 1: No, the project description says, “You are required to study … one or more subsystems of the Linux kernel which provide some basic kernel functionality”. You do not need to study the whole Linux kernel for your project.

“Memory Management”, would be an example of a Linux subsystem that would be of suitable scope for the project. “Process Scheduling” would be another example of a Linux subsystem that would be of suitable scope for the project.
