+Description: Add lu_ref support to ldlm_lock
+Details : lu_ref support for ldlm_lock and ldlm_resource. See lu_ref patch.
+ lu_ref fields ->l_reference and ->lr_reference are added to ldlm_lock
+ and ldlm_resource. LDLM interface has to be changed, because code that
+ releases a reference on a lock, has to "know" what reference this is.
+ In the most frequent case
+
+ lock = ldlm_handle2lock(handle);
+ ...
+ LDLM_LOCK_PUT(lock);
+
+ no changes are required. When any other reference (received _not_ from
+ ldlm_handle2lock()) is released, LDLM_LOCK_RELEASE() has to be called
+ instead of LDLM_LOCK_PUT().
+
+ Arguably, changes are pervasive, and interface requires some discipline
+ for proper use. On the other hand, it was very instrumental in finding
+ a few leaked lock references.
