Function data_model::flexible_array::vec_with_array_field

pub fn vec_with_array_field<T: Default, F>(count: usize) -> Vec<T>

The kernel API has many structs that resemble the following Foo structure:

#[repr(C)]
struct Foo {
   some_data: u32,
   entries: __IncompleteArrayField<__u32>,
}

In order to allocate such a structure, size_of::<Foo>() would be too small because it would not include any space for entries. To make the allocation large enough while still being aligned for Foo, a Vec<Foo> is created. Only the first element of Vec<Foo> would actually be used as a Foo. The remaining memory in the Vec<Foo> is for entries, which must be contiguous with Foo. This function is used to make the Vec<Foo> with enough space for count entries.
