Yes, rename events actually consist of at least two: move from and move to, and they carry the same cookie, so that userspace could combine them into single transaction. All others use zero, so I decided to put PID of the caller there. This does not look perfect of course, but we can not change the structure layout, so rename events can not be changed to carry additional PID field.
