^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 		of ocfs2 locking supported by the filesystem.  This version
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 		covers how ocfs2 uses distributed locking between cluster
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 		nodes.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) 		The protocol version has a major and minor number.  Two
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 		cluster nodes can interoperate if they have an identical
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 		major number and an overlapping minor number - thus,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) 		a node with version 1.10 can interoperate with a node
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) 		sporting version 1.8, as long as both use the 1.8 protocol.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) 		A cluster plugin is required to use ocfs2 in a cluster.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) 		There are currently two available plugins:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) 		* 'o2cb' - The classic o2cb cluster stack that ocfs2 has
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) 			used since its inception.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) 		* 'user' - A plugin supporting userspace cluster software
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) 			in conjunction with fs/dlm.
