From 24d292b894273495f9664bb495e575f8cb7e8cac Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Fri, 24 Dec 2010 01:32:43 +0000 Subject: NFS: Move cl_state_owners and related fields to the nfs_server struct NFSv4 migration needs to reassociate state owners from the source to the destination nfs_server data structures. To make that easier, move the cl_state_owners field to the nfs_server struct. cl_openowner_id and cl_lockowner_id accompany this move, as they are used in conjunction with cl_state_owners. The cl_lock field in the parent nfs_client continues to protect all three of these fields.
