I haven't looked at the guts of their flock to see if they ignore len as well. I think if you zero those 2 fields in linux_to_bsd_flock64, you'll be fine. Hopefully, Marcel will have some idea of what the "right" thing to do here is. Drew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-emulation" in the body of the message
