* locking semantics of the file system using the protocol. It should
* be somewhere else, I'm sure, but right now it isn't.
*
+ * With version 11, we separate out the filesystem locking portion. The
+ * filesystem now has a major.minor version it negotiates. Version 11
+ * introduces this negotiation to the o2dlm protocol, and as such the
+ * version here in tcp_internal.h should not need to be bumped for
+ * filesystem locking changes.
+ *
+ * New in version 11
+ * - Negotiation of filesystem locking in the dlm join.
+ *
+ * New in version 10:
+ * - Meta/data locks combined
+ *
+ * New in version 9:
+ * - All votes removed
+ *
+ * New in version 8:
+ * - Replace delete inode votes with a cluster lock
+ *
+ * New in version 7:
+ * - DLM join domain includes the live nodemap
+ *
+ * New in version 6:
+ * - DLM lockres remote refcount fixes.
+ *
* New in version 5:
* - Network timeout checking protocol
*
* - full 64 bit i_size in the metadata lock lvbs
* - introduction of "rw" lock and pushing meta/data locking down
