|
* both are used. dev represents an index / identifier of a device or
|
|
* filesystem, and I'm unsure whether a negative value has any meaning in that
|
|
* context. Hence my choice of using an unsigned integer. Negative values, if
|
|
* we encounter them, will just get typecasted into a positive value. No
|
|
* information is lost in this conversion, and the semantics remain the same.
