[PATCH] mm: quieten OOM killer noise
We now print statistics when invoking the OOM killer, however this
information is not rate limited and you can get into situations where the
console is continually spammed.
For example, when a task is exiting the OOM killer will simply return
(waiting for that task to exit and clear up memory). If the VM continually
calls back into the OOM killer we get thousands of copies of show_mem() on
the console.
Use printk_ratelimit() to quieten it.
