So would I, but unfortunately that is a different issue :-(. This
PR relates to the problem where umount -f fails when the server is
alive and responding, but something is holding an extra reference
on the filesystem root vnode. This problem also exists in a number
of other filesystems in the tree, all of which were fixed in -current
by the vflush() changes.
