You measure the delta of the reads. Your process can be scheduled away and when it comes back two events can be available, so they are read right after each other and trigger your check. Your measuring method is wrong. You really want to measure the delta of the timer events in the kernel via ktime_get(), not the delta of something else in userspace.
