NAME

6       trace_softirq_raise - called immediately when a softirq is raised
7

SYNOPSIS

9       void trace_softirq_raise(struct softirq_action * h,
10                                struct softirq_action * vec);
11

ARGUMENTS

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

DESCRIPTION

20       The h parameter contains a pointer to the softirq vector number which
21       is raised.  vec is NULL and it means h includes vector number not
22       softirq_action. When used in combination with the softirq_entry
23       tracepoint we can determine the softirq raise latency.
