This patch adds the infrastructure required to support cephfs quotas as it is currently implemented in the ceph fuse client. Cephfs quotas can be set on any directory, and can restrict the number of bytes or the number of files stored beneath that point in the directory hierarchy. Quotas are set using the extended attributes 'ceph.quota.max_files' and 'ceph.quota.max_bytes', and can be removed by setting these attributes to '0'.

|
* 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.
