From 1f0e890dba5b0f543fea47732116b1c65d55614e Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 24 Jun 2010 15:11:43 -0400 Subject: NFSv4: Clean up struct nfs4_state_owner The 'so_delegations' list appears to be unused. Also eliminate so_client. If we already have so_server, we can get to the nfs_client structure.
