This is the next revision of the SCSI event notification infrastructure patchset, enabling SATA Asynchronous Notification ("AN") for CD/DVD devices that support it. For devices that support SATA AN (only very recent ones do), this means that HAL and other userspace utilities no longer need to repeatedly poll the CD/DVD device to determine if the user has changed the media. This revision takes into account James' comments from earlier today, modulo the following notes: * I think the various event attributes should always be present, for all devices at all times. If various events are not supported, the attribute will of course return zero (false, not supported). * I do not think this work should be blocked behind a revamp of the attribute group interface. * I was slack and did not bother to implement the 'set' operation for the attributes. This can easily be done at a later time in a separate patch. It is not a merge stopper to have the driver exclusively control the event mask, rather than driver+sysfs. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
