Doc Text:
.osd_scrub_chunk_max is honored also with objects that have many clones Previously, deep scrubbing of objects that had a number of clones could impact the client performance. With this enhancement, deep scrubbing honors the limit specified by the `osd_scrub_chunk_max` parameter even when an object has many clones. As a result, the impact on client performance is limited.
