Before updating superblock of slave disks, desired_state value is set for the target state of the slave disks. But it forgets to check MD_DISK_FAILFAST flag. Then start_arrays() calls ADD_NEW_DISK ioctl-call and pass the state without MD_DISK_FAILFAST. Currenlty it does not generate any problem because kernel does not care MD_DISK_FAILFAST flag.
