I think it would be wrong for full wouldn't it? It could mean that
the client would skip the read, thus not getting the intended ENOSPC
error. For null I agree.
The full plugin always reads as 0 successfully. It is only writes that
differ (successfully ignored vs ENOSPC) between the two plugins.

Yes, the language bindings lag behind what's available because they
aren't generated ...
I still need to revive my patches for adding fua support to python
bindings...
