- The sysfs directory names are changed from stxmy[n] to the names in
  devices.txt. Below is an example for the first tape drive:
  /sys/class/scsi_tape/
  |-- nst0
  |-- nst0a
  |-- nst0l
  |-- nst0m
  |-- st0
  |-- st0a
  |-- st0l
  `-- st0m

- Name generation for non-default number of modes fixed so that same
  minors get same names even with different number of modes.

- devfs minor generation fixed to work with non-default number of modes

- The alignment requirement is printed in the line logged when a tape is
  attached.
