I'll put it on my todo list for the next time I have a Windows VM
sitting around. I do recall testing Samba alongside Windows when doing
the initial implementation, but QAR is very FS block / allocation size
specific, so 1:1 behaviour isn't straightforward (nor is it required by
the FSCTL_QUERY_ALLOCATED_RANGES / FSCTL_SET_ZERO_DATA specs).
Cheers, David
