>Environment:

FreeBSD 2.2.6-STABLE i386, recent build

>Description:

Let's do the following on -STABLE with /dev/sd3c being a normal FFS:

root@voyager:~>mount -o async /dev/sd3c /mnt

root@voyager:~>mount | grep sd3
/dev/sd3c on /mnt (asynchronous, local)

root@voyager:~>cd /mnt

root@voyager:/mnt>umount /mnt
umount: /mnt: Device busy

root@voyager:~>mount | grep sd3
/dev/sd3c on /mnt (local)


As we see, after doing the unsuccessful umount, the filesystem is no
more mounted async. This happens only to the async option; other
mount options (like ro or noatime) are not changed.

>How-To-Repeat:

	see above
