Thanks Andrii. __sync_fetch_and_add doesn't seem to work as expected, it is adding the increment, but it is returning the wrong value.
I am actually hitting the same issue mentioned here: https://lists.iovisor.org/g/iovisor-dev/topic/problems_with/23670176?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,20,23670176

Can anyone suggest if it is fixed recently? I am on 4.15 kernel.

Thanks,
Kanthi
