[PATCH] DVD-RAM rewritable again

[Pat LaVarre <p.lavarre@ieee.org>]

Jens A:

Can I help by offering the trivial patch shown here?  Or can I help in
some other way?

I ask because I see this patch makes my PATAPI DVD-RAM disc as
rewritable as it was in 2.4.26.

Per my understanding of your instructions, I defer, until 2.4.28, the
non-trivial work of making PATAPI and USB DVD-RAM discs behave the same.

Per my understanding of your instructions, I leave USB DVD-RAM discs not
rewritable until 2.4.28, since those discs have not been rewritable at
least since 2.4.26.
