[SCSI] sr,sd: send media state change modification events
This will send for a card reader slot (remove/add media): UEVENT[1187091572.155884] change /devices/pci0000:00/0000:00:1d.7/usb5/5-2/5-2:1.0/host7/target7:0:0/7:0:0:0 (scsi) UEVENT[1187091572.162314] remove /block/sdb/sdb1 (block) UEVENT[1187091572.172464] add /block/sdb/sdb1 (block) UEVENT[1187091572.175408] change /devices/pci0000:00/0000:00:1d.7/usb5/5-2/5-2:1.0/host7/target7:0:0/7:0:0:0 (scsi) and for a DVD drive (add/eject media): UEVENT[1187091590.189159] change /devices/pci0000:00/0000:00:1f.1/host4/target4:0:0/4:0:0:0 (scsi) UEVENT[1187091590.957124] add /module/isofs (module) UEVENT[1187091604.468207] change /devices/pci0000:00/0000:00:1f.1/host4/target4:0:0/4:0:0:0 (scsi) Userspace gets events, even for unpartitioned media. This unifies the event handling for asynchronoous events (AN) and events caused by perodical polling the device from userspace.
