I'm talking about the cases where this caused a bug here.

Passing "struct dst_entry **dst" as an argument.

It's just stupid, and a relic of code that wants to return
a route and a locallized error at the same time.

I'm saying that in the end we should simply return "struct dst_entry
*" from such functions.

Anyways, please submit your original patch in this thread so I
can get this simple case fixed in net-next.
