3.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Sachin Prabhu <[email protected]> commit 2477bc58d49edb1c0baf59df7dc093dce682af2b upstream. While attempting to clone a file on a samba server, we receive a STATUS_INVALID_DEVICE_REQUEST. This is mapped to -EOPNOTSUPP which isn't handled in smb2_clone_range(). We end up looping in the while loop making same call to the samba server over and over again. The proposed fix is to exit and return the error value when encountered with an unhandled error.
