    async_tx: build-time toggling of async_{syndrome,xor}_val dma support · 7b3cc2b1
    Dan Williams authored
    ioat3.2 does not support asynchronous error notifications which makes
    the driver experience latencies when non-zero pq validate results are
    expected.  Provide a mechanism for turning off async_xor_val and
    async_syndrome_val via Kconfig.  This approach is generally useful for
    any driver that specifies ASYNC_TX_DISABLE_CHANNEL_SWITCH and would like
    to force the async_tx api to fall back to the synchronous path for
    certain operations.
