No one is running pre-argonaut. In addition one of the argonaut features (NOSRCADDR) has been required since day one (and a half, 2.6.34 vs 2.6.35) of the kernel client. Allow for the possibility of reusing these feature bits later. Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Reviewed-by: Sage Weil <sage@redhat.com>

|
* 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 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.
