[PATCH] DVD-R capability flag set incorrectly, /proc formatting fix
From John McKell <mckellj@iomega.com>:
This patch for scsi/sr.c and cdrom/cdrom.c persuades
/proc/sys/dev/cdrom/info to report that connecting a drive via USB
rather than ATAPI in fact does not make it able to write DVD-R.
Without this patch, when sr0 and hdd are the same type of device
connected via USB and ATAPI respectively, I see:
$ cat /proc/sys/dev/cdrom/info:
drive name: sr1 sr0 hdd
...
Can write CD-R: 1 0 0
Can write CD-RW: 1 0 0
Can read DVD: 0 0 0
Can write DVD-R: 1 1 0
Can write DVD-RAM: 0 0 0
Can read MRW: 0 0 0
Can write MRW: 0 0 0
With this patch applied, instead I see:
$ cat /proc/sys/dev/cdrom/info:
drive name: sr1 sr0 hdd
...
Can write CD-R: 1 0 0
Can write CD-RW: 1 0 0
Can read DVD: 0 0 0
Can write DVD-R: 0 0 0
Can write DVD-RAM: 0 0 0
Can read MRW: 0 0 0
Can write MRW: 0 0 0
The sr1 device in particular is an ordinary CD-RW that in fact cannot
write DVD-R.
While messing with this code, I also thought to tweak the /proc
formatting to align the tabbed columns.
