Date: Sun, 22 Mar 2015 19:04:02 +1100 From: Herbert Xu <herbert@...dor.apana.org.au> To: "David S. Miller" <davem@...emloft.net>, Thomas Graf <tgraf@...g.ch>, Eric Dumazet <eric.dumazet@...il.com>, Patrick McHardy <kaber@...sh.net>, Josh Triplett <josh@...htriplett.org>, "Paul E. McKenney" <paulmck@...ux.vnet.ibm.com>, netdev@...r.kernel.org Subject: [v2 PATCH 4/10] netlink: Use default rhashtable hashfn This patch removes the explicit jhash value for the hashfn parameter of rhashtable. The default is now jhash so removing the setting makes no difference apart from making one less copy of jhash in the kernel.
