Hello all, and thank you so much for the review, Steven and Masami. I'm currently considering replacing the `max_ofs` output with `length`. Please let me know your thoughts. With the current design, a memory range of an event is an inclusive range of [ofs, max_ofs + 4096]. I found the `+4096` part confusing during the ureadahead's upstreaming work. Replacing `max_ofs` with `length` makes the range specified by an event much more concise.
This makes sense to me. Matthew, have any comments on this? Thanks, -- Steve
