+  DESCRIPTION
+
+    After a locking error we want to quit the locking of the table(s).
+    The test case in the bug report for Bug #18544 has the following
+    cases: 1. Locking error in lock_external() due to InnoDB timeout.
+    2. Locking error in get_lock_data() due to missing write permission.
+    3. Locking error in wait_if_global_read_lock() due to lock conflict.
+
+    In all these cases we have already set the lock type into the lock
+    data of the open table(s). If the table(s) are in the open table
+    cache, they could be reused with the non-zero lock type set. This
+    could lead to ignoring a different lock type with the next lock.
+
+    Clear the lock type of all lock data. This ensures that the next
+    lock request will set its lock type properly.
