TRACE_SOFTIRQ_EXIT(9) IRQ TRACE_SOFTIRQ_EXIT(9)NAMEtrace_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.
