I don't think the following test is needed:
if (tvp->v_mount != fdvp->v_mount)
tvp = NULL;
else
vref(tvp);
as VOP_RENAME() is not intended to support cross-mount renames; any call
that ever did that would be an error.
My only concern with leaving the test in is that it might imply to some
future programmers that they need to worry about a cross-mount rename.
Take care,
Bill
