Re: [PATCH] sched: Fix NULL mm dereference in sched_mm_cid_after_execve()

  void sched_mm_cid_after_execve(struct task_struct *t)
  {
-    sched_mm_cid_fork(t);
+    if (t->mm)
+        sched_mm_cid_fork(t);
  }

Hi,

It's a correct solution, but I have a small suggestion that putting the 'mm'
checking into sched_mm_cid_fork(), just like sched_mm_cid_exit().

Best regards,
