Sorry for the late replies, was away.

The refcount req business all rests on the poll command implementation,
which is basically a straight port of the aio version. So I guess not
surprising if it suffers from the same reference issue. I'll take a look
at the patches that went into aio and apply the same fix(es) to
io_uring.

I'll let Al expand on the AF_UNIX socket issue.

Thanks for getting this merged! I'll be on top of squashing the above
two cases asap.
