Subject: [PATCH 2.5] capability flag for ATAPI MO devices
Date: Thu, 12 Jun 2003 14:33:01 +0200 (CEST) [thread overview]
Message-ID: <Pine.LNX.4.44.0306121428410.2153-100000@neptune.local> (raw)
Hi Jens,
I though I already sent this version of the patch to you, but I can't
find it in my sent-mail folder, so I may have forgotten to do so.
This just adds a capability flag to ide-cd.{c,h} and cdrom.h so that we
may later know this device is an MO drive (needed for write support).
Please apply.
