4.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Richard Weinberger <richard@xxxxxx>
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.
Cc: Andreas Gruenbacher <agruenba@xxxxxxxxxx>
Fixes: 2b88fc21ca ("ubifs: Switch to generic xattr handlers")
