We recently had a discussion on the cdrecord-support mailing list
about the need to eject a CD/DVD-R after burning to be able to
mount it.

This has been a known issue under Linux for some time:

http://lkml.indiana.edu/hypermail/linux/kernel/9604.3/0377.html

It is a more serious annoyance with laptop drives that cannot
close their trays without the help of a human hand.

Has this issue been fixed in recent kernels, and if so, does anyone
know about what release the change was made?

Also, is there an ioctl or other way to force the kernel/driver to
invalidate the read cache or other stored data of a specific
drive/media (not the system as a whole) without having to physically
eject the media?


Cheers and thanks in advance,

Mike Shell
