I have just looked at this patch and reading the code it looks incorrect to me.

 void set_thread_affinity( struct thread *thread, affinity_t affinity )
 {
+    if (!(affinity & thread->process->affinity))
+    {
+        set_error( STATUS_INVALID_PARAMETER );
+        return;
+    }

If the process affinity is 0x05 and I try and set a thread affinity of 0x03
this should fail and this will not be the case with the above code.
