…C count Fix yield-count accounting in the scanner, A send-side batching policy is also introduced: the send ULT defers flushing until at least REBUILD_SEND_BATCH_MIN OIDs are queued or REBUILD_SEND_BATCH_TIMEOUT_SEC seconds have elapsed. Without batching, a fast scanner floods the destination rank with many small RPCs, exhausting IB receive buffers and triggering timeouts. This is especially severe during reintegration, where all OIDs are concentrated on a single target rank. Signed-off-by: Wang Shilong <shilong.wang@hpe.com>
