-		Note that once a key has been loaded, it will no longer be
-		possible to enable metadata modification.
+		Echoing a value is additive, the new value is added to the
+		existing initialization flags.
+
+		For example, after::
+
+		  echo 2 ><securityfs>/evm
+
+		another echo can be performed::
+
+		  echo 1 ><securityfs>/evm
+
+		and the resulting value will be 3.

+		Note that once an HMAC key has been loaded, it will no longer
+		be possible to enable metadata modification. Signaling that an
+		HMAC key has been loaded will clear the corresponding flag.
+		For example, if the current value is 6 (2 and 4 set)::
+
+		  echo 1 ><securityfs>/evm
+
+		will set the new value to 3 (4 cleared).
+
+		Loading an HMAC key is the only way to disable metadata
+		modification.
 
 		Until key loading has been signaled EVM can not create

+ * After BFS we get a lock dependency path (linked via ->parent of lock_list),
+ * printing out each lock in the dependency path will help on understanding how
+ * the deadlock could happen. Here are some details about dependency path
+ * printing:
+ *
+ * 1)	A lock_list can be either forwards or backwards for a lock dependency,
+ * 	for a lock dependency A -> B, there are two lock_lists:
+ *
+ * 	a)	lock_list in the ->locks_after list of A, whose ->class is B and
+ * 		->links_to is A. In this case, we can say the lock_list is
+ * 		"A -> B" (forwards case).
+ *
+ * 	b)	lock_list in the ->locks_before list of B, whose ->class is A
+ * 		and ->links_to is B. In this case, we can say the lock_list is
+ * 		"B <- A" (bacwards case).
+ *
+ * 	The ->trace of both a) and b) point to the call trace where B was
+ * 	acquired with A held.
+ *
+ * 2)	A "helper" lock_list is introduced during BFS, this lock_list doesn't
+ * 	represent a certain lock dependency, it only provides an initial entry
+ * 	for BFS. For example, BFS may introduce a "helper" lock_list whose
+ * 	->class is A, as a result BFS will search all dependencies starting with
+ * 	A, e.g. A -> B or A -> C.
+ *
+ * 	The notation of a forwards helper lock_list is like "-> A", which means
+ * 	we should search the forwards dependencies starting with "A", e.g A -> B
+ * 	or A -> C.
+ *
+ * 	The notation of a bacwards helper lock_list is like "<- B", which means
+ * 	we should search the backwards dependencies ending with "B", e.g.
+ * 	B <- A or B <- C.
