| Doc Text: |
.Laggy clients are now evicted only if there are no laggy OSDs
Previously, monitoring performance dumps from the MDS would sometimes show that the OSDs were laggy, `objecter.op_laggy` and `objecter.osd_laggy`, causing laggy clients (dirty data could not be flushed for cap revokes).
With this enhancement, if the `defer_client_eviction_on_laggy_osds` option is set to true and a client gets laggy because of a laggy OSD then client eviction will not take place until OSDs are no longer laggy.
