If a scsi_device supports async notification for media change, then let user
space know this capability exists by creating a new sysfs entry
"media_change_notify", which will be 1 if it is supported, and 0 if not
supported. Create a routine which allows scsi devices to send a uevent when
media change events occur.

Ping?

Re-Ping?

This patch works (it has been working for months), is ACK'd by me, addresses some of the feedback given in August, and has not received any comments despite the SCSI maintainers being To'd or CC'd for weeks (months, if you include the older thread).

Further, this patch is required to round out interrupt-driven media change notification, that which eliminates the CD-ROM polling that userspace has done since the dawn of time.

It was not in the merge window SCSI push, while being in -mm for a while and linux-scsi having the patch for a while. Which means, if the silence continues, it must wait 4-6 months for 2.6.25 release, for no apparent reason.
