NAME
trace_softirq_exit - called immediately after the softirq handler returnsSYNOPSIS
- 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.
