Name:ftrace_graph_probe_sched_switch
Proto:static void ftrace_graph_probe_sched_switch(void *ignore, bool preempt, struct task_struct *prev, struct task_struct *next)
Type:void
Parameter:
| Type | Parameter | Name |
|---|---|---|
| void * | ignore | |
| bool | preempt | |
| struct task_struct * | prev | |
| struct task_struct * | next |
| 427 | If Both enabled by default (can be cleared by function_graph tracer flags Then Return |
| 430 | timestamp = race_clock_local(): the simplest and least coherent tracing clock.* Useful for tracing that does not cross to other CPUs nor* does it go through idle events. |
| 432 | ftrace_timestamp = timestamp |
| 435 | If Not ftrace_timestamp Then Return |
| 442 | timestamp -= ftrace_timestamp |
