From 7981c8a659143173882dda43b3056a777faeeb7b Mon Sep 17 00:00:00 2001 From: Anna Schumaker Date: Tue, 10 Jan 2017 11:39:53 -0500 Subject: [PATCH] NFS: Create a single nfs4_setup_sequence() function The inline ifdef lets us put everything in a single place, rather than having two (very similar) versions of this function.
