Quotas have been a supported feature in certain applications of CephFS (notably: Openstack Manila shares). The kernel client has recently added full support for quotas so now this is a stable feature. This is a test-only BZ.
More information on quotas here: https://docs.ceph.com/docs/master/cephfs/quota/
Testing is completed for this feature on 5.0 builds.
