Description

When generate_past_intervals_parallel() is called from load_pgs() the superblock hasn't been published yet. This causes PG::_calc_past_interval_range() to get a 0 for oldest_map when doing osd->get_superblock().oldest_map. This can cause *start to be earlier then the oldest OSDMap that is available especially when handling an pg that was imported with ceph-objectstore-tool. In that case the last_epoch_clean could be earlier then the oldest map available.
