If you do the following:
# mount -t iso9660 /dev/cdrom /cdrom -o ro,norock
# ls /cdrom
then you get an oops. (Actually I don't think this would have happened
if I'd had a Joliet CD in my drive, but I was using an old backup
disc, generated with mkisofs)
Patch is attached below. Although I am running 2.1.117 I've checked
2.1.119 and it applies cleanly. Fix is trivial and makes sense looking
at the following code.
I have a question: why is the default mapping set to 'a' (Acorn)?
Surely it should be set to 'n' (normal)? Of course, I wouldn't have
found this problem then ;-)
