Please provide info about this system (RAID controller?) and a sample
smartctl command line which triggers these warnings.
Unfortunately the kernel does not tell which ioctl is "a deprecated SCSI
ioctl".
smartmontools 7.4 and 7.5 no longer use the deprecated
SCSI_IOCTL_SEND_COMMAND, except if one of the following options for very
old controllers are used:
'-d 3ware,N'
'-d marvell' (deprecated and subject to remove)
In all other cases, SG_IO (version 3 or version 4) or a vendor specific
ioctl is used.
