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.
