Yeah, I noticed that too after filing that bugreport,
indeed, the problem not in the size of the structures,
but in the changed way - old inline functions used the
deprecated ring_kmask & ring_kentries, while the new
ones uses new ring_mask & ring_entries.

It is either Depends: liburing2 > $version, or, if the ABI is broken like
this, it is Depends: liburing3 > $newversion (with the soname bump).

At any rate, this is not exactly samba problem, but it affects samba.
