Not a canonical way, but both should work (POLLIN for CQEs).
Do you have a simple test case for us to reproduce?
Hm, no, I cannot. I must have faced another bug, I was not able to
produce a minimal test case and my attempt to reproduce my earlier bug
in a larger test case was not succesful.
Sounds like polling is ok, let us know if there is any problem
One issue which remains is that attempting to use REGISTER_FILES on
io_uring A with io_uring B's file descriptor returns EBADF. I saw a
comment in the kernel source explaining this, but it's a bit contrived
and the error case is not documented.
Surely should be updated if not mentioned
