From 19d87ca3623956494b517f3abe0caf2616d55457 Mon Sep 17 00:00:00 2001 From: Bryan Schumaker Date: Mon, 30 Jul 2012 16:05:21 -0400 Subject: NFS: Split out remaining NFS v4 inode functions Somehow I missed this in my previous patch series, but these functions are only needed by the v4 code and should be moved to a v4-only file. I wasn't exactly sure where I should put these functions, so I moved them into nfs4super.c where I could make them static.
