I just tried to create a filesystem on kernel 4.6.0, grow it on 4.6.0, then copy it to another machine with 4.4.4. However that didn't reproduce the bug, so I couldn't verify if the patch fixes the bug. (Maybe 4.4.4 is too new?) Can you help me to understand under what circumstances this bug would appear, as far as you understand what's happening?
