I am getting this error when I ran it on 6.3-rc but as you noted, I do
see it work on 6.2 (I tested on 6.2-rc6 a few minutes ago). Perhaps
related to one of of the iov_iter/netfs changes in 6.3?

running it with 6.2-rc6 I did notice 3 share reconnects (and a session
reconnect) which was strange but the test passed ...
