Hi!
I wonder how I missed this, as this is a feature I've been waiting for
for some time...

You could test this with e.g. a sparse lvm lv, i.e. --virtualsize option
of lvcreate, no?
After running the attached quickly hacked up test script on a patched

patchset simply incompatible with 3.3 or is this an actual bug?
