I have already stated my position. Let's not reinvent the wheel and use
the standard printk throttling. If there are cases where oom reports
cause more harm than good I am open to add a knob to allow disabling it
altogether (it can be even fine grained one to control whether to dump
show_mem, task_list etc.).
But please let's stop this dubious one-off approaches.
