the task_struct

Hi,allThese days i tried to study the structure task_truct in linux kernel 2.65.32,but the member of the struct is so gigantic.What' more,many materials are just to list the struct,but not show the meaning of the members in task_struct,and many books of kernel study also do not explian the use of the members.But,i want to understand the structure deeply.Now,i am in a big trouble,and i need help from you.Anybody who can give me a hand? thanks!
