4.3-stable review patch. If anyone has any objections, please let me know.
------------------ From: Al Viro <[email protected]> commit e2c9e0b28e146c9a3bce21408f3c02e24ac7ac31 upstream. ex->ee_block is not host-endian (note that accesses of other fields of *ex right next to that line go through the helpers that do proper conversion from little-endian to host-endian; it might make sense to add similar for ->ee_block to avoid reintroducing that kind of bugs...)
