... and there goes smartmontools support until v5.34 is
released.

More generally (not just 3ware), several smartmontools
users have complained to me about the warnings sent to
their log every time smartd wakes up (30 minutes) and
checks their SCSI disks in recent 2.6 versions. One
deprecated warning should be sufficient.

 From an application maintainer's point of view sysfs is
relatively new (only in lk 2.6) and just starting to settle
down.
