I would object to this if only because of the horrible name.
C++ is not a good language to take ideas from, and "new()" was not it's
best feature to begin with. "k_new()" is just disgusting.
I'd call it something like "alloc_struct()" instead, which tells you
exactly what it's all about. Especially since we try to avoid typedefs in
the kernel, and as a result, it's basically almost always a struct thing.
That said, I'm not at all sure it's worth it. Especially not with all the
various variations on a theme (zeroed, arrays, etc etc).
Quite frankly, I suspect you would be better off just instrumenting
"sparse" instead, and matching up the size of the allocation with the type
it gets assigned to.
