      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;drm/msm: Fix shrinker deadlock&lt;/p&gt;
&lt;p&gt;With PROVE_LOCKING on an Snapdragon X1 and VM reclaim pressure, we see:&lt;/p&gt;
