[PATCH 02/11] NFS: Change nfs4_get_session() to take an nfs_client structure

[<Anna.Schumaker@Netapp.com>]

From: Anna Schumaker <Anna.Schumaker@Netapp.com>

pNFS only has access to the nfs_client structure, and not the
nfs_server, so we need to make this change so the function can be used
by pNFS as well.
