    I'm fine with this, but I'd like to get some feedback on my last proposal regarding somehow relating […]

    Not sure if I understood you correctly.

    For the receive side:
    In the poll backend the msghdr is only a local variable that goes out of scope as soon as iofd_poll_ofd_cb_recvmsg_sendmsg() returns, in io_uring the msghdr is free()d at the end of iofd_uring_handle_recv(). In both cases I expect the user might want to keep msg around for longer.

    Then there's msg->pending which is a msg from (a/multiple) previous receive call so it's not clear what msghdr(s) it belongs to anymore.
