perf_put_aux_event
__perf_install_in_contextCross 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_event_context_sched_out
perf_event_context_sched_in
perf_event_enable_on_execEnable all of a task's events that have been marked enable-on-exec.* This expects task == current.
