Después de la reserva del hardware de la PMU, la memoria requerida para las PMU en las que se instalará el evento se asigna mediante allocate_buffers() y alloc_sampling_buffer(). Esto se hace fuera de la protección mutex. Sin la protección mutex, dos o más invocaciones simultáneas de perf_event_init() pueden ejecutarse en paralelo.
