FWIW, samba built against the relatively new liburing-2.3 does not

This turned out to be debian packaging issue, but it might affect
others too. liburing 2.3 breaks ABI by changing layout of the main
struct io_uring object in a significant way.

I don't see where this changes the struct size:
- unsigned pad[4];
+ unsigned ring_mask;
+ unsigned ring_entries;
+
+ unsigned pad[2];
But I see a problem when you compile against 2.3 and run against 2.2
as the new values are not filled.
The problem is the mixture of inline and non-inline functions...
The packaging should make sure it requires the version is build against...
