NAME

6       trace_softirq_exit - called immediately after the softirq handler
7       returns
8

SYNOPSIS

10       void trace_softirq_exit(struct softirq_action * h,
11                               struct softirq_action * vec);
12

ARGUMENTS

14       h
15           pointer to struct softirq_action
16
17       vec
18           pointer to first struct softirq_action in softirq_vec array
19

DESCRIPTION

21       The h parameter contains a pointer to the struct softirq_action that
22       has handled the softirq. By subtracting the vec pointer from the h
23       pointer, we can determine the softirq number. Also, when used in
24       combination with the softirq_entry tracepoint we can determine the
25       softirq latency.
