Seems to me that "/lib/udev/cdrom_id --eject-media $device" as called by
/lib/udev/rules.d/60-cdrom_id.rules is trying too hard. It should
respect the lock flag on the device, maybe with a "--force" option to
eject regardless. Anyway this is surely a udev bug not a kernel bug.

Title:
cd drive lock does not work after oneiric upgrade
Status in “udev” package in Ubuntu:
Triaged
Bug description:
Because the eject button on my laptop's CD drive is highly susceptible
to being pressed accidentally, I use "eject -i 1" to lock the CD drive
from being ejected when the button is pressed.
After upgrading to oneiric, this stopped working. stracing eject shows
that it is correctly finding the /dev/sr0 node, opening it, and
ioctl'ing it correctly, but if I press the eject button afterwards,
the drive still ejects.
