Name:Similar to event_function_call() + event_function(), but hard assumes IRQs* are already disabled and we're on the right CPU.
Proto:static void event_function_local(struct perf_event *event, event_f func, void *data)
Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
struct perf_event * | event | |
event_f | func | |
void * | data |
304 | cpuctx = __get_cpu_context(ctx) |
306 | struct perf_event_context * task_ctx = NULL |
310 | If task Then |
311 | If task == TASK_TOMBSTONE Then Return |
317 | perf_ctx_lock(cpuctx, task_ctx) |
320 | If task == TASK_TOMBSTONE Then Go to unlock |
323 | If task Then |
329 | If is_active Then |
330 | If WARN_ON_ONCE(task != current process) Then Go to unlock |
333 | If WARN_ON_ONCE(task_ctx != ctx) Then Go to unlock |
336 | Else |
337 | WARN_ON_ONCE( & ctx != ctx) |
341 | unlock : |
