Re: [PATCH net] datagram: When peeking datagrams with offset < 0 don't skip empty skbs

with epoll, there's no new edge trigger since event is already at level. How will they avoid busy-waiting? And won't this secondary coordination obviate the need for offset peeking? -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center

Re: [PATCH net] datagram: When peeking datagrams with offset < 0 don't skip empty skbs

Understood. By the way, what were the usecases for the peek offset feature? Also, do they apply to non-peeking recv? -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center

Re: [PATCH net] datagram: When peeking datagrams with offset < 0 don't skip empty skbs

hould the reading return an empty datagram? This would indicate to the caller that there was a datagram there, which was skipped over. That's how we deal with empty datagrams anyway. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
