Re: PROBLEM: 2.6.25: sr0 cdrom does not change medium size on medium change

[Ingo Saitz <Ingo.Saitz@xxxxxxxxxxxxxxxxxxxx>]

I did some git bisecting during which I found it does matte wether you
let the drive settle before mounting or not during the 2.6.25 devcycle.
So after being struck at some random position I redid the bisection.

This commit applies to: changing the medium (cd/dvd), waiting until the
drive settles and mounting it. The kernel no longer changes the size of
the medium in /sys/block/sr0/size, giving read errors for bigger mediae.

    [SCSI] sr: update to follow tray status correctly

    Based on an original patch from: David Martin <tasio@xxxxxxxxx>

    When trying to get the drive status via ioctl CDROM_DRIVE_STATUS, with
    no disk it gives CDS_TRAY_OPEN even if the tray is closed.

    ioctl works as expected with ide-cd driver.
