We found with newer kernels we started seeing the cdrom device showing
up in /proc/partitions, but it was not there before. Looking into this I found
that commit d27769ec... block: add GENHD_FL_NO_PART_SCAN introduces this change
in behavior. It's not clear to me from the commit's changelog if this change was
intentional or not. This comment still remains:
/* Don't show non-partitionable removeable devices or empty devices */
so I've decided to send a patch to restore the behavior of not printing
unpartitionable removable devices.
Thanks
Josh

After commit d27769ec... block: add GENHD_FL_NO_PART_SCAN, /proc/partitions
started printing removable devices with only one partition. This is different
than prior to the commit. This restores /proc/partitions to behave as it did
before.
