SYNOPSIS
#include <sys/param.h>
#include <sys/vnode.h>
int
VOP_RENAME(struct vnode *fdvp, struct vnode *fvp,
struct componentname *fcnp, struct vnode *tdvp, struct vnode *tvp,
struct componentname *tcnp);
DESCRIPTION
This renames a file and possibly changes its parent directory. If the
destination object exists, it will be removed first.
Its arguments are:
fdvp The vnode of the old parent directory.
fvp The vnode of the file to be renamed.
fcnp Pathname information about the file's current name.
tdvp The vnode of the new parent directory.
tvp The vnode of the target file (if it exists).
tcnp Pathname information about the file's new name.
LOCKS

ref count bumped on entry. The VOP routine is expected to vrele(9) both
prior to returning.
The destination directory and file are locked as well as having their ref
count bumped. The VOP routine is expected to vput(9) both prior to
returning.
