3.16.57-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Ilya Dryomov <[email protected]> commit e573427a440fd67d3f522357d7ac901d59281948 upstream. This feature bit restricts older clients from performing certain maintenance operations against an image (e.g. clone, snap create). krbd does not perform maintenance operations.
