Anyway my problem was solved by the filter in custom tracepoints (for instance, tracing/events/kmem/filter). Also, I used trace_*_enabled() to first check if tracepoint is enabled and take ktime_get() only after that. This solved my initial issue. Thanks David, Yang and the Linux community for helping me identify my issue and solve it. Best Regards, Shivank
