From 60ccd4ec4170c9487e3792322626acd160197bce Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sat, 29 Sep 2007 17:48:19 -0400 Subject: NFS: Remove nfs_begin_data_update/nfs_end_data_update The lower level routines in fs/nfs/proc.c, fs/nfs/nfs3proc.c and fs/nfs/nfs4proc.c should already be dealing with the revalidation issues.
