I actually thought I had submitted those patches as part of the thin
provisioning update. Looks like I held them back for some reason. I'll
check my notes to figure out why and get the kit merged forward ASAP!

I hadn't thought of that use case. Going to be a bit tricky given how
GET LBA STATUS works...
