Change the second argument of vflush() to an integer that specifies 2001-05-16T18:04:37+00:00 Ian Dowse iedowse@FreeBSD.org 2001-05-16T18:04:37+00:00 0864ef1e8a449b1533c7e0ea673e9614aaa9a81f the number of references on the filesystem root vnode to be both expected and released. Many filesystems hold an extra reference on the filesystem root vnode, which must be accounted for when determining if the filesystem is busy and then released if it isn't busy. The old `skipvp' approach required individual filesystem xxx_unmount functions to re-implement much of vflush()'s logic to deal with the root vnode. All 9 filesystems that hold an extra reference on the root vnode got the logic wrong in the case of forced unmounts, so `umount -f' would always fail if there were any extra root vnode references.
