A collegue fo mine had the problem that it was possible to vnconfig -u a vn device that was currently in use. This strikes me as odd. When looking through the da device code, I notice a similar problem. Suppose I have a zip fdisk mounted with a disklabel and 2 ufs partitions on it. When I mount both partitions, the disk will be locked. But it will be unlocked at the first unmount. I guess there should be a refcounter that keeps track of the amount of opens and only unlock devices at the last close. Same for vn.c. Any comments? -Guido To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
