Name
trace_softirq_exit —
called immediately after the softirq handler returns
Synopsis
void trace_softirq_exit ( | struct softirq_action * h, |
| | struct softirq_action * vec); |
Arguments
h
pointer to struct softirq_action
vec
pointer to first struct softirq_action in softirq_vec array
Description
The h parameter contains a pointer to the struct softirq_action
that has handled the softirq. By subtracting the vec pointer from
the h pointer, we can determine the softirq number. Also, when used in
combination with the softirq_entry tracepoint we can determine the softirq
latency.
