more than 2 sec, start time: 38181400013

it would be good to have same time-format (seconds.nanosec)

[38181400013] to [42181875177]

same as above

Thanks for your review.

I have also thought about whether it needs to be modified here, and the
intuitive reading here will be a little troubled. It is ok for me to
modify :-)

+static void rtnl_relase_btrace(void)

should this be release_btrace?

will fix.
