Thanks .. I have another question. I was trying to practice some kernel process management APIs as in
http://reiber.org/nxt/pub/Linux/LinuxKernelDevelopment/Linux.Kernel.Development.3rd.Edition.pdf
(Linux Kernel Development by Robert Love, 3rd edition).
I am not sure how to practice the code snippet given in the text book. I
can understand the theory but do not find a way to practice. For
example: I want to read a process 'struct task_struct' to find it
parent's process identifier, how many tasks are in which state, creating
kernel threads etc?
Any idea?
