Now that the sg version 4 interface is supported: - with ioctl(SG_IO) for synchronous/blocking use - with ioctl(SG_IOSUBMIT) and ioctl(SG_IORECEIVE) for async/non-blocking use Plus new ioctl(SG_IOSUBMIT_V3) and ioctl(SG_IORECEIVE_V3) potentially replace write() and read() for the sg version 3 interface. Bump major driver version number from 3 to 4. The main new feature is the removal of the fixed 16 element array of requests per file descriptor. It is replaced by a xarray (eXtensible array) in their parent which is a sg_fd object (i.e. a file descriptor). The sg_request objects are not freed until the owning file descriptor is closed; instead these objects are re-used when multiple commands are sent to the same file descriptor.
