Here is the version of the patch, I will include in the cdrecord-1.5a5
release. I modified the Bus # to be an integer and the directory to
be 'linux' to allow most users to patch their kernels.
I have currently no Linux with SCSI at all and would be happy to
get test results from people who have more SCSI busses.
I put the new cdrecord alpha out this moment. It os located on:
ftp://ftp.fokus.gmd.de/pub/unix/cdrecord/alpha
I must be missing something here, but I'd like to know why a user program needs
to know the SCSI bus number at all. The LUN is necessary because it must go in
the CDB, but I don't see how the SCSI bus number matters to a user program.
The user must specify the /dev/sg<x> SCSI generic device, which makes the
mapping to bus and Target ID automatic.
Please clarify.
Leonard
