One other thing,
sock_poll() will only ll_poll if the flag was set _and_ the socket has a
none-zero value in sk->sk_ll_usec so you still only poll on sockets
that were enabled for LLS, not on every socket.
But sockets are default enabled for LLS.
sock_init_data()
{
...
sk->sk_ll_usec = sysctl_net_ll_poll;

}
Yes, if you want to globally enable.
But now that we have the socket option, you can leave the global
setting at 0 and only enable specific sockets via the socket option.
(I have tested this with a modified sockperf and it works.)
I missed something, you need sysctl_net_ll_poll to be non-zero
for poll to even try.
So maybe add another sysctl value for poll?
maybe sysctl_net_ll_poll for poll
and sysctl_net_ll_read for socket reads?
