+ * Notes on deprecation:
+ *
+ * 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,
+ *    mimic) 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, MON_METADATA, MIMIC)
+ *
+ *    because 13.2.z (mimic) did not care if its peers advertised this
+ *    feature bit.
+ *
+ *  - In the second phase we stop advertising the the bit and call it
+ *    RETIRED.  This can normally be done 2 major releases
+ *    following the one in which we marked the feature DEPRECATED.  In
+ *    the above example, for 15.0.z (octopus) we can say:
+ *
+ *      DEFINE_CEPH_FEATURE_RETIRED( 2, 1, MON_METADATA, MIMIC, OCTOPUS)
+ *
+ *  - The bit can be reused in the next release that will never talk to
+ *    a pre-octopus daemon (13 mimic or 14 nautlius) that advertises the
+ *    bit: in this case, the 16.y.z (P-release).
+ *
+ * This ensures that no two versions who have different meanings for
+ * the bit ever speak to each other.
+ */
+
+/*
+ * Notes on the kernel client:
+ *
+ * - "X" means that the feature bit has been advertised and supported
+ *   since kernel X
+ *
+ * - "X req" means that the feature bit has been advertised and required
+ *   since kernel X
+ *
+ * The remaining feature bits are not and have never been used by the
+ * kernel client.
