Can I allocate a View w/ both WithoutInitializing & AllowPadding?

[mhoemmen]

Is it possible to allocate a View with both WithoutInitializing and AllowPadding? I don't see a way to nest those allocation parameters. Do they just nest, as they do with the string label?
#319 would fix this because I wouldn't need to pass in AllowPadding at run time; the compile-time memory trait would suffice.

trilinos/Trilinos#423 depends on this.

View<...> a( view_alloc( "label" , WithoutInitializing , AllowPadding ) , N0 , N1 , ... );

Thanks @hcedwar ! But see #325. Also, when I try this, I get the following static_assert:

...

Here is the line of code in question:

typename dual_view_type::t_dev d_view (Kokkos::Experimental::view_alloc (label, Kokkos::Experimental::WithoutInitializing, Kokkos::Experimental::AllowPadding), lclNumRows, numCols);

I'm not sure whether this is a question or bug, so I removed the "question" label.

[mhoemmen]

The answer to my question is "yes," so I'm calling this bug closed. Thanks all!

Assigning to Fall, I don't want closed issues on backlog. Its kind of weird to have completion rate higher than 0% on backlog ....
