<p>This is similar to the &quot;acquire&quot; ordering, except that an ordering is
only guaranteed with operations that &quot;depend on&quot; the result of the load.
However consume loads are usually much faster than acquire loads on
architectures with a weak memory model since they don't require memory
fence instructions.</p>
<p>The exact definition of &quot;depend on&quot; is a bit vague, but it works as you
would expect in practice since a lot of software, especially the Linux
kernel, rely on this behavior.</p>
