Documentation update to KernelShark

Hi Yordan,

Can you apply this patch to the KernelShark repo:

  https://patchwork.kernel.org/project/linux-trace-devel/patch/[email protected]/

Also, you probably should have your name added to the PatchWork so that
I can delegate KernelShark patches to you, and that will make it easier
for what is needed for KernelShark.

Do you have PatchWork account? If not, we should get you one (I Cc'd
[email protected] to let them know you need one too).
