4.7-stable review patch. If anyone has any objections, please let me know.
------------------ From: Richard Weinberger <[email protected]> commit 17ce1eb0b64eb27d4f9180daae7495fa022c7b0d upstream. UBIFS uses full names to work with xattrs, therefore we have to use xattr_full_name() to obtain the xattr prefix as string.
