We'll either need to add handling to empty REQ_FLUSH requests to all of them or figure out a way to prevent them getting sent. That is assuming they'll simply ignore REQ_FLUSH/REQ_FUA on normal writes. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
