**Caller**
Name	Describe
event_function
event_function_local	Similar to event_function_call() + event_function(), but hard assumes IRQs* are already disabled and we're on the right CPU.
perf_pmu_resched
__perf_install_in_context	Cross CPU call to install and enable a performance event* Very similar to remote_function() + event_function() but cannot assume that* things like ctx->is_active and cpuctx->task_ctx are set.
perf_pmu_sched_task	This function provides the context switch callback to the lower code* layer. It is invoked ONLY when the context switch callback is enabled.* This callback is relevant even to per-cpu events; for example multi event
perf_event_context_sched_in
perf_rotate_context
perf_event_enable_on_exec	Enable all of a task's events that have been marked enable-on-exec.* This expects task == current.
