…#17652) After PS leader switch, ds_rebuild_regenerate_task() only regenerates rebuild tasks for DOWN/DRAIN/UP targets. RECLAIM tasks are not regenerated because reintegrated targets are already UPIN. This leaves orphaned rpt on every target with a stale leader term, whose IV updates are silently dropped by the new leader (no matching rgt). The result is sp_rebuilding > 0 permanently, blocking EC aggregation and causing system-wide performance degradation. Fix: detect stale leader term in rebuild_tgt_status_check_ult() and abort the orphaned rpt. Signed-off-by: Wang Shilong <shilong.wang@hpe.com>
