53 These drivers will always see the REQ_FLUSH and REQ_FUA bits as they sit
56 to be implemented for bios with the REQ_FLUSH bit set. For real device
57 drivers that do not have a volatile cache the REQ_FLUSH and REQ_FUA bits
58 on non-empty bios can simply be ignored, and REQ_FLUSH requests without
68 support required, the block layer completes empty REQ_FLUSH requests before
69 entering the driver and strips off the REQ_FLUSH and REQ_FUA bits from
