Merge branch 'nfs-for-2.6.40' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6
* 'nfs-for-2.6.40' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6: SUNRPC: Support for RPC over AF_LOCAL transports SUNRPC: Remove obsolete comment SUNRPC: Use AF_LOCAL for rpcbind upcalls SUNRPC: Clean up use of curly braces in switch cases NFS: Revert NFSROOT default mount options SUNRPC: Rename xs_encode_tcp_fragment_header() nfs,rcu: convert call_rcu(nfs_free_delegation_callback) to kfree_rcu() nfs41: Correct offset for LAYOUTCOMMIT NFS: nfs_update_inode: print current and new inode size in debug output NFSv4.1: Fix the handling of NFS4ERR_SEQ_MISORDERED errors NFSv4: Handle expired stateids when the lease is still valid SUNRPC: Deal with the lack of a SYN_SENT sk->sk_state_change callback...
