* 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.

* "Frags" are a way to describe a subset of a 32-bit number space,
* using a mask and a value to match against that mask. Any given frag
* (subset of the number space) can be partitioned into 2^n sub-frags.
*
* Frags are encoded into a 32-bit word:
* 8 upper bits = "bits"
* 24 lower bits = "value"
* (We could go to 5+27 bits, but who cares.)
*
* We use the _most_ significant bits of the 24 bit value. This makes
* values logically sort.
*
* Unfortunately, because the "bits" field is still in the high bits, we
* can't sort encoded frags numerically. However, it does allow you
