Process scheduling

         I want to understand the flow of code of process scheduler of
linux kernel. What I have understood is that
The task marks itself as sleeping,
puts itself on a wait queue,
removes itself from the red-black tree of runnable, and
calls schedule() to select a new process to execute.

for Waking back up
The task is set as runnable,
removed from the wait queue,
and added back to the red-black tree.

Can I get the details of which function does what? in sched/core.c and in
I am concerned only with fair scheduler. There are so many functions in
these two files that I am totally confused.
