DESCRIPTION
     The vflush() function removes any vnodes in the vnode table that belong
     to the given mount structure.

     Its arguments are:

     mp            The mount point whose vnodes should be removed.

     rootrefs      The number of references expected on the root vnode.
                   vrele(9) will be invoked on the root vnode rootrefs times.

     flags         The flags indicating how vnodes should be handled.

                   FORCECLOSE      If set, busy vnodes will be forcibly
                                   closed.

                                   will be skipped.

                   WRITECLOSE      If set, only regular files currently opened
                                   for writing will be removed.
