As same as KProbe/DTrace. Can you use OProfile for something other tnan profiling ? Probably yes and this answer opens: probably it will be good prepare some common code for KProbe and Oprofile.
I don't see an overlap here, except maybe the possibility of delivering sample events into the kprobes framework
Not sure what you mean with "delivering into the kprobes framework" kprobes currently only uses printk which really isn't up to the task of any significant data delivery. The IBM people have relayfs to solve this problem, eventually this should be probably merged too. Without something like relayfs i don't see any way to compete with dtrace.
