<pre>I am trying to implementing P0901r0 [0] in jemalloc. The signature of the new
memory allocation function looks like this:
typedef struct {
void *ptr;
size_t usize;
} smallocx_return_t;
smallocx_return_t je_smallocx(size_t size, int flags);
I have to set the alloc_size attribute for smallocx_return_t.ptr, but AFAICT
this is not currently possible.
