(If this works out fine then i&#039;ll propagate these changes back into the CFS backport, for wider testing.)&lt;/i&gt;&quot;  He went on to describe the other main changes in the development branch of the process scheduler:&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;&quot;I&#039;ve also included the latest and greatest group-fairness scheduling patch from Srivatsa Vaddagiri, which can now be used without containers as well (in a simplified, each-uid-gets-its-fair-share mode). This feature (CONFIG_FAIR_USER_SCHED) is now default-enabled.&lt;/p&gt;
&lt;p&gt;&quot;Peter Zijlstra has been busy enhancing the math of the scheduler: we&#039;ve got the new &#039;vslice&#039; forked-task code that should enable snappier shell commands during load while still keeping kbuild workloads in check.&quot;&lt;/p&gt;&lt;/blockquote&gt;
