Subject: [PATCH 3/3] nvme: use the DMA_ATTR_NO_WARN attribute
Date: Mon, 1 Aug 2016 19:59:50 -0300 [thread overview]
Message-ID: <1470092390-25451-4-git-send-email-mauricfo@linux.vnet.ibm.com> (raw)
In-Reply-To: <1470092390-25451-1-git-send-email-mauricfo@linux.vnet.ibm.com>
Use the DMA_ATTR_NO_WARN attribute for the dma_map_sg() call of the nvme
driver that returns BLK_MQ_RQ_QUEUE_BUSY (not for BLK_MQ_RQ_QUEUE_ERROR).
