Hi John,

I have added my Reviewed-by to patch 2/3.

Regarding the other two patches in this series: I do not agree with
patch 3/3. As I have explained, I am concerned that that patch breaks
existing block drivers.

Are patches 1/3 and 3/3 necessary? Or in other words, is patch 2/3
sufficient to fix the use-after-free?

Thanks,

Bart.
