Quite frankly, you don't need the zeroing. That's what __GFP_ZERO does in
the flags.
That said, I'm not at all sure that it's at all more readable to add some
new abstraction layer and do
struct random_struct *ptr;
ptr = alloc_struct(random_struct, 1, GFP_KERNEL | __GFP_ZERO);
than just doing a
ptr = kmalloc(sizeof(*ptr), GFP_KERNEL | __GFP_ZERO);
or
ptr = kzalloc(sizeof(*ptr), GFP_KERNEL);
(and adding the zeroing variant of alloc_struct() just adds *more*
confusing issues).
The fact is, type safety in this area is probably less important than the
code just being readable. And have fifteen different interfaces to memory
allocation just isn't ever going to readable - regardless of how good they
are individually.
