If you look at ceph_features.h in master, there are macros that make it explicit when a feature is deprecated and when it can be resused. Once luminous is out we'll have another 10+ bits available. Right now the only ones we can't reuse are the ones that affect client behavior; those we have to be more careful deprecating in order to preserve support for old clients. sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
