Re: [PATCH] Identify which executable object the userspace addressbelongs to. Store thread group leader id, and use it to lookup theaddress in the process's map. We could have looked up the addresson thread's map, but the thread might not exist by the time we arecalled. The process might not exist either, but if you are readingtrace_pipe, that is unlikely.

Is this kindergarten? Take a look at seq_path - what you want
is the combination of d_path + mangle_path and the combination of two
would be rather trivial. In fact I'd say you don't even need the helper
but just make mangle_path global (and document it while you're at it)
and then use it.
