/* * Notes on deprecation: * * A *major* release is a release through which all upgrades must pass * (e.g., jewel). For example, no pre-jewel server will ever talk to * a post-jewel server (mon, osd, etc). * * For feature bits used *only* on the server-side: * * - In the first phase we indicate that a feature is DEPRECATED as of * a particular release. This is the first major release X (say, * jewel) that does not depend on its peers advertising the feature. * That is, it safely assumes its peers all have the feature. We * indicate this with the DEPRECATED macro. For example, * * DEFINE_CEPH_FEATURE_DEPRECATED( 2, 1, MONCLOCKCHECK, JEWEL) * * because 10.2.z (jewel) did not care if its peers advertised this * feature bit. * * - In the second phase we stop advertising the bit and call it * RETIRED. This can normally be done in the *next* major release * following the one in which we marked the feature DEPRECATED. In * the above example, for 12.0.z (luminous) we can say: * * DEFINE_CEPH_FEATURE_RETIRED( 2, 1, MONCLOCKCHECK, JEWEL, LUMINOUS) * * - The bit can be reused in the first post-luminous release, 13.0.z * (m). * * This ensures that no two versions who have different meanings for * the bit ever speak to each other. */
