Hardware Environment: IBM Thinkpad R40 2722-GDG

Problem Description:
Multiple directory entries in /proc/ide after removing and inserting a ultrabay
device with the use of hdparm -U/-R

0 think:/proc/ide# ll
total 2
-r--r--r--    1 root     root            0 Feb 17 10:19 drivers

dr-xr-xr-x    3 root     root            0 Feb 17 10:19 ide1
dr-xr-xr-x    3 root     root            0 Feb 17 10:19 ide1
dr-xr-xr-x    3 root     root            0 Feb 17 10:19 ide1
dr-xr-xr-x    3 root     root            0 Feb 17 10:19 ide1
dr-xr-xr-x    3 root     root            0 Feb 17 10:19 ide1
dr-xr-xr-x    3 root     root            0 Feb 17 10:19 ide1
-r--r--r--    1 root     root            0 Feb 17 10:19 piix
0 think:/proc/ide#



Steps to reproduce:
(that's the same the scripts from the hdparm's contrib directory do)

- remove drive from ultrabay
- hdparm -U 1 /dev/hda
- insert drive
- hdparm -R 0x170 0 0 /dev/hda

now we have another ide1 directory in /proc/ide, but the old one should b reused.
