- * Put a new Volume entry in the Volume list. This
- * effectively reserves the volume so that it will
- * not be mounted again.
- *
- * If the device has any current volume associated with it,
- * and it is a different Volume, and the device is not busy,
- * we release the old Volume item and insert the new one.
- *
- * It is assumed that the device is free and locked so that
- * we can change the device structure.
- *
- * Some details of the Volume list handling:
- *
- * 1. The Volume list entry must be attached to the drive (rather than
- * attached to a job as it currently is. I.e. the drive that "owns"
- * the volume (reserved, in use, mounted)
- * must point to the volume (still to be maintained in a list).
- *
- * 2. The Volume is entered in the list when a drive is reserved.
- *
- * 3. When a drive is in use, the device code must appropriately update the
- * volume name as it changes (currently the list is static -- an entry is
- * removed when the Volume is no longer reserved, in use or mounted).
- * The new code must keep the same list entry as long as the drive
- * has any volume associated with it but the volume name in the list
- * must be updated when the drive has a different volume mounted.
- *
- * 4. A job that has reserved a volume, can un-reserve the volume, and if the
- * volume is not mounted, and not reserved, and not in use, it will be
- * removed from the list.
- *
- * 5. If a job wants to reserve a drive with a different Volume from the one on
- * the drive, it can re-use the drive for the new Volume.
- *
- * 6. If a job wants a Volume that is in a different drive, it can either use the
- * other drive or take the volume, only if the other drive is not in use or
- * not reserved.
- *
- * One nice aspect of this is that the reserve use count and the writer use count
- * already exist and are correctly programmed and will need no changes -- use
- * counts are always very tricky.
- *
- * The old code had a concept of "reserving" a Volume, but was changed
- * to reserving and using a drive. A volume is must be attached to (owned by) a
- * drive and can move from drive to drive or be unused given certain specific
- * conditions of the drive. The key is that the drive must "own" the Volume.
- * The old code had the job (dcr) owning the volume (more or less). The job was
- * to change the insertion and removal of the volumes from the list to be based
- * on the drive rather than the job.
- *
- * Return: VOLRES entry on success
- * NULL volume busy on another drive
