Typically you will be operating on a vnode, which has previously been looked up by another function. - vnop_* functions are to be implemented by Filesystems, and the vnode_* functions (KPI) in turn call these. The VNOP_* functions are immediate wrappers around the functions implemented by filesystems, and exported by those filesystems in their VNOP export tables.
