So only the kernel macro is wrong, please fix it to

By doing this, you're loosing the type information. Why not
defining it both in user-space and kernel as union {_type _name;
__aligned_u64 _name ## _data_u64; }
The kernel can't use the pointer, so why define it for it?
The kernel code could use this type directly. For example, if we have a
ULP that wants to use esp flow action directly, it'll have to use this
as a pointer.
Are there some macros or something that check it in the kernel?
