NFS: Optimise NFS close()
Close-to-open cache consistency rules really only require us to flush out writes on calls to close(), and require us to revalidate attributes on the very last close of the file. Currently we appear to be doing a lot of extra attribute revalidation and cache flushes. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
