From 6de7e12f53a154d35d9aceae718b764ada23e430 Mon Sep 17 00:00:00 2001 From: Anna Schumaker Date: Mon, 9 Jan 2017 16:51:52 -0500 Subject: [PATCH] NFS: Use nfs4_setup_sequence() everywhere This does the right thing depending on if we have a session, rather than needing to handle this manually in multiple places.
