>Description:
wfd driver code tries to give wd driver first crack at ioctl's,
but incorrectly interprets internal error and never gets to send
eject to ATAPI device.
>How-To-Repeat:
Put zip disk in internal IDE zip drive, do:

ioctl (fd, _IO('c',24), 0)

where fd is the corresponding wfd open file descriptor. Disk
does not eject.
>Fix:
This kernel patch fixes it:
