I did some testing with this patch (using 3.0rc2 for reproducing it upstream, but the same behaviour
with 2.6.39 and e73e079bf128d68284efedeba1fbbc18d78610f9 applied).
ext2 and ext3 FS on the USB sticks are working fine, however I get the following oops when performing
the same test with the CDROM part of a sandisk cruzer:

Steps to reproduce:
1. mount /dev/sr0 /mnt # Mount fails
2. umount /mnt # Message about not being mounted
3. mount /dev/sr0 /mnt # [sr0] messages appears in kernel log
4. remove USB stick # USB disconnect message
5. umount /mnt # above error message
I mount the /dev/sr0 in /mnt and remove it before calling umount. I had to repeat the mount as it seemed to fail the first time (calling umount /mnt in-between). The second mount succeeded with some errors reported by the sr0.
Full logs attached as text file.
