+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.

+they still need more work; once complete, they can be moved into the

+LP5523 can drive up to 9 channels. Leds can be controlled directly via
+the led class control interface. Channels have generic names:

 DESCRIPTION
 -----------
@@ -24,23 +28,53 @@ There are several variants of perf trace:
   available via 'perf trace -l').  The following variants allow you to
   record and run those scripts:
 
-  'perf trace record <script>' to record the events required for 'perf
-  trace report'.  <script> is the name displayed in the output of
-  'perf trace --list' i.e. the actual script name minus any language
-  extension.
+  'perf trace record <script> <command>' to record the events required
+  for 'perf trace report'.  <script> is the name displayed in the
+  output of 'perf trace --list' i.e. the actual script name minus any
+  language extension.  If <command> is not specified, the events are
+  recorded using the -a (system-wide) 'perf record' option.
 
-  'perf trace report <script>' to run and display the results of

+  'perf trace report <script> [args]' to run and display the results

+  not specified, the events are recorded using the -a (system-wide)
+  'perf record' option.  If <script> has any required args, they
+  should be specified before <command>.  This mode doesn't allow for
+  optional script args to be specified; if optional script args are
+  desired, they can be specified using separate 'perf trace record'
+  and 'perf trace report' commands, with the stdout of the record step
+  piped to the stdin of the report script, using the '-o -' and '-i -'
+  options of the corresponding commands.
+
+  'perf trace <top-script>' to both record the events required for
+  <top-script> and to run the <top-script> using 'live-mode'
+  i.e. without writing anything to disk.  <top-script> is the name
+  displayed in the output of 'perf trace --list' i.e. the actual
+  script name minus any language extension; a <top-script> is defined
+  as any script name ending with the string 'top'.
+
+  [<record-options>] can be passed to the record steps of 'perf trace
+  record' and 'live-mode' variants; this isn't possible however for
+  <top-script> 'live-mode' or 'perf trace report' variants.
 
   See the 'SEE ALSO' section for links to language-specific
   information on how to write and run your own trace scripts.

 -D::
 --dump-raw-trace=::
         Display verbose dump of the trace data.
