Log Message:
Pull up revision 1.6 (requested by wrstuden in ticket #424):
Since VOP_UPCALL() has been a long time in coming, add this partial
fix for layered-file-removal. It will work for the case of accessing
and deleting a file through the layered file system. Accessing via
the layer and deleting on the underlying still won't work, nor will
accessing via complicated structures (like two umap layers over a
given file systems).
We still need VOP_UPCALL(), but this is better than things were before.
This patch has been discussed off & on for a while. This incarnation
was tested by hannken at netbsd dot org.
