From 0a8ebba943dd89bdd57c5dab5a66932f690847d9 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sat, 31 Jul 2010 14:29:06 -0400 Subject: [PATCH] NFS: nfs_rename() should not have to flush out writebacks We don't really support nfs servers that invalidate the file handle after a rename, so precautions such as flushing out dirty data before renaming the file are superfluous.
