The function however\nlooped purex-\u003eentry_count times starting at ring_ptr. As entry_count\nincludes the head, this consumed one entry too many: it stamped\nRESPONSE_PROCESSED on the next, unrelated IOCB and advanced the ring\npast it, silently dropping a legitimate firmware response. The head\nIOCB's signature was also never marked.\n\nMark the head processed and account for it, then consume only the\nentry_count - 1 continuation IOCBs, matching __qla_copy_purex_to_buffer().",
