 Modified Files:
        src/sys/kern [netbsd-6]: vfs_lookup.c
        src/sys/miscfs/genfs [netbsd-6]: layer_vnops.c
 Log Message:
 Pull up following revision(s) (requested by dholland in ticket #664):
        sys/kern/vfs_lookup.c: revision 1.195
        sys/miscfs/genfs/layer_vnops.c: revision 1.51
 In layer_lookup(), clear *vpp before returning EROFS, as otherwise a
 stale value can be returned and this causes a diagnostic panic in
 In relookup(), clear *vpp before calling VOP_LOOKUP, as is done in
 lookup_once(), as an additional precautionary measure.
 (in theory both of these fixes are not required together)
 Should fix PR 47040.
