Subject: Re: [PATCH net-next v3 0/2] udp: Fix multicast performance issues.

From: David Held <>
Date: Tue, 15 Jul 2014 23:28:30 -0400

> Fix performance issues with listening to many different multicast
> sockets on different addresses with the same port. Instead of always
> using hash1, fall back to hash2 lookup when hash1 lookup is long.
> Patch 1 is a general cleanup and simplification which also makes the
> main implementation in Patch 2 simpler.
> Eric's recent change 63c6f81cdde5 avoided this being an issue in early
> demux. This makes it work for regular delivery as well.
> v1->v2
>  - updated hash collision detection
> v2->v3
>  - avoid flushing under lock unnecessarily at ARRAY_SIZE boundary

Series applied, thanks a lot David.
