Hi.
I've found that -current kernel couldn't mount CD-Extra disks on
ATAPI CD drives.
For example:
Starting track = 1, ending track = 14, TOC size = 122 bytes
track start duration block length type

Tracks 1-13 are normal CD-DA in the first session,
and track 14 is the ISO9660 filesystem which consists of
XA Mode 2 Form 1 sectors (2048bytes/sector) in the second session.
This disk can be mounted on my SCSI CD drive,
but not on my ATAPI CD drive (with EINVAL).
I applied the following patch,
and then I can successfully mount the disk.
Is this a right treatment?
