Sure. Following Documentation/process/security-bugs.rst I had only offered the reproducers on request; since you'd like them in blktests, I'll post them to linux-block shortly, unless you'd rather have them off-list until the fixes are merged. One test covers this patch, and two more cover the fc and NUMD patches of this series. Thanks for the review, Andrea
