Subject: [Livid-dev] DVD patch for 2.2 kernel, where?

Hi,

Where can i find the DVD ioctl patch for a 2.2 kernel ?

there URL:
   http://www.rpi.edu/~veliaa/linux-dvd
given in the README of css-auth (in the CVS) is no more?

maybe the patch could be added in the CVS archive in the css-auth dir?

I have asked Matthew to set up a cdrom-patch module so that
I can submit a current patch, but to my knowledge it is
not there yet.

I'd also like to clarify a few things about the patch
confusion, as I see several "misguided" comments from
time to time.

- The dvd stuff that is in 2.3 (and the patches for
2.2 on my site) are based on Andrew's patches in that
most of the code is just directly copied. The only
difference as seen from a user space application is
that I eliminated the key1/key2 and called them
both key - this has caused some confusion and I am
completely willing to change it back, since having
people placing #ifdef's in their code should not
be necessary. Having looked at the NetBSD DVD
stuff just now, they use key too. So maybe we
people should just bite the bullet and accept
that key is the name of the member - this doesn't
work for people with Andrew's patch, though.

- Andrew's patch is for ide-cd.c, which means that
it only works on ATAPI drives. The way I integrated
it allows it to work equally well on SCSI and ATAPI
without any code duplication. Some people mistakingly
dub my patch "the scsi patch" - this is just plain
wrong, it is no more SCSI than ATAPI specific. If
people would actually bother to look at the code,
this is very apparent.

Hope this clears up the confusion - I'm open
for input as always.

		       SCO Files Lawsuit Against IBM

March 7, 2003 - The SCO Group filed legal action against IBM in the State 
Court of Utah for trade secrets misappropriation, tortious interference, 
unfair competition and breach of contract. The complaint alleges that IBM 
made concentrated efforts to improperly destroy the economic value of
