4.2.8-ckt3 -stable review patch. If anyone has any objections, please let me know.

From: Miklos Szeredi <miklos@szeredi.hu>
commit 97daf8b97ad6f913a34c82515be64dc9ac08d63e upstream.
When ovl_copy_xattr() encountered a zero size xattr no more xattrs were copied and the function returned success. This is clearly not the desired behavior.
