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

Even if that was true, which would be avery sad world I should be
easy enough for you or anyone to look at what seq_path does and how
to have a version that doesn't use the seq_file insterface.  Takes
about two minutes with most of the time spent on finding where seq_file
is implemented.
