/* The process supports new-style OSDMap encoding. Monitors also use * - In the first phase we indicate that a feature is DEPRECATED as of

#define CEPH_FEATURE_MDS_INLINE_DATA (1ULL<<40) * That is, it safely assumes its peers all have the feature. We
#define CEPH_FEATURE_CRUSH_TUNABLES3 (1ULL<<41) * indicate this with the DEPRECATED macro. For example,
#define CEPH_FEATURE_OSD_PRIMARY_AFFINITY (1ULL<<41) /* overlap w/ tunables3 */ *

#define CEPH_FEATURE_MDS_QUOTA (1ULL<<47) * the above example, for 12.0.z (luminous) we can say:
