Does this check cause trouble to anyone or to a specific kernel configuration?
In other words, do we really need to remove these checks? I think that these
checks are useful as documentation to people who read the SCSI target code.
The target code is already hard to follow so I think any documentation,
especially documentation in the form of code that is checked at runtime, is
welcome.

Thanks,

Bart.
