liburing 2.3 broke binary compatibility without bumping the soname.
In liburing.h in 2.3, structures io_uring_cq and io_uring_sq changed
their sizes. Both of these structures are parts of io_uring structure
which the main part of the API. Here's the difference:

This does not look like it is changing the size actually, - I haven't
noticed it adjusts pad[] accordingly. So this is not the issue here.
But the end result is the same: samba compiled with liburing 2.2 does
not work with runtime liburing 2.3, and samba compiled with liburing
2.3 does not work with runtime liburing 2.2.
I'm just too tired now to dig further.
