smbd maps Windows byte range locks onto POSIX locks.
kernel oplock support could help you find out if
the client has a lease on the file (through smbd).

I doubt you are guaranteed that the windows client
has an oplock or a byte range lock on the file you
are interested in (unless you know the client application
really well).
