-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.
