vflush

The vflush() function removes any vnodes in the vnode table that belong to the given mount structure.
Its arguments are:

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.

The flags indicating how vnodes should be handled.
If set, busy vnodes will be forcibly closed.
If set, vnodes with the VV_SYSTEM flag set will be skipped.
If set, only regular files currently opened for writing will be removed.

A value of 0 is returned if the flush is successful; otherwise, EBUSY will be returned.
