+ * Test for CVE-2017-5754 - pcrypt mishandles freeing instances.
+ *
+ * The test works by adding and then removing pcrypt-AEAD instances.
+ * See commit d76c68109f37 crypto: pcrypt - fix freeing pcrypt instances.
+ *
+ * If the bug is present then this will probably crash the kernel, but also
+ * sometimes the test simply times out.
