Description

radosgw's datalog trim logic remembers the to_marker of its call to cls_log_trim(), and avoids calling it again until the marker advances past that. however, cls_log_trim() has a hardcoded limit of 1000 entries per call, and is not guaranteed to trim all the way to this to_marker. as a result, radosgw may stop trying to trim even though many entries may still remain
