		What: /proc/<pid>/oom_adj
		When: August 2012
		Why: /proc/<pid>/oom_adj allows userspace to influence the oom killer's
		badness heuristic used to determine which task to kill when the kernel
		is out of memory.

		The badness heuristic has since been rewritten since the introduction of
		this tunable such that its meaning is deprecated. The value was
		implemented as a bitshift on a score generated by the badness()
		function that did not have any precise units of measure. With the
		rewrite, the score is given as a proportion of available memory to the
		task allocating pages, so using a bitshift which grows the score
		exponentially is, thus, impossible to tune with fine granularity.

		A much more powerful interface, /proc/<pid>/oom_score_adj, was
		introduced with the oom killer rewrite that allows users to increase or
		decrease the badness score linearly. This interface will replace
		/proc/<pid>/oom_adj.

		A warning will be emitted to the kernel log if an application uses this
		deprecated interface. After it is printed once, future warnings will be
		suppressed until the kernel is rebooted.
