19 * @name FsRtlBalanceReads
20 * @implemented NT 5.2
21 *
22 * The FsRtlBalanceReads routine sends an IRP to an FTDISK Driver
23 * requesting the driver to balance read requests across a mirror set.
24 *
25 * @param TargetDevice
26 * A pointer to an FTDISK Device Object.
27 *
28 * @return The NTSTATUS error code returned by the FTDISK Driver.
29 *
30 * @remarks FTDISK is a Software RAID Implementation.
