Let me explain how the patches are usually merged. - kernel/kprobes.c related patches go through the tip tree. - kernel/trace/* patches go through the tracing tree. So traditionally(?) I think this series go through the tip tree, but since the biggest user of kprobes is tracing and the kprobes fix now involves tree-wide fixes as you can see in this series, I think it is a good timing to move kprobes to tracing tree.
