If buffer size were large enough to hold messages from out_of_memory(),
I would like to use it for out_of_memory() because delaying SIGKILL
due to waiting for printk() to complete is not good. Surely we can't
hold all messages because amount from dump_tasks() is unpredictable.
Maybe we can hold all messages from dump_header() except dump_tasks().

But isn't it essentially same with

which Linus does not want?
