Hi,
Looking for a way to traverse the runqueue, so that I could get the contents of the runqueue. Initial reading tells that sched.h has ched_entity structure, which holds some of the data for it, like the
struct rb_node run_node;
Also read that redblack tree is used to hold the elements with "vruntime" as the index of it.
Could anyone give a way forward to doing this.

I think, for simple traversing, you could just use for_each_process,
unless you wanna find out something related to the rb tree. And, with
my limited knowledge, rbtree.h doesn't include any traversing
function.
