TRACE_SOFTIRQ_EXIT(9)							IRQ						     TRACE_SOFTIRQ_EXIT(9)

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.
