From 11b58ba146ccd7b105c4962c75f2e744053c85bc Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 24 Mar 2015 00:50:22 +1100 Subject: [PATCH] netlink: Use default rhashtable hashfn This patch removes the explicit jhash value for the hashfn parameter of rhashtable. As the key length is a multiple of 4, this means that we will actually end up using jhash2. Signed-off-by: Herbert Xu Acked-by: Thomas Graf Signed-off-by: David S.
