3.16.70-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: "Eric W. Biederman" <[email protected]> commit 40cc394be1aa18848b8757e03bd8ed23281f572e upstream. In the rare and unsupported case of a hostname list nfs_parse_devname will modify dev_name. There is no need to modify dev_name as the all that is being computed is the length of the hostname, so the computed length can just be shorted.
