yeah. There's a help section at the top of the trace which explains the
other fields too:
_------=> CPU#
/ _-----=> irqs-off
| / _----=> need-resched
|| / _---=> hardirq/softirq
||| / _--=> preempt-depth
|||| /
||||| delay
cmd pid ||||| time | caller
\ / ||||| \ | /
privoxy-12926 1.Ns1 0us : ktime_get_ts (ktime_get)
the function name in braces is the parent function. So in this case the
trace entry means we called ktime_get_ts() from ktime_get().
