Message-Id: <20140825.161224.1108200625385309828.davem@davemloft.net> Date: Mon, 25 Aug 2014 16:12:24 -0700 (PDT) From: David Miller <davem@...emloft.net> To: tgraf@...g.ch CC: eric.dumazet@...il.com, netdev@...r.kernel.org Subject: using rhashtable in inethash During the Networking Workshop I mentioned converting the inet hash tables over to rhashtable so that we don't allocate this insanely large hash table at boot time which goes largely unused. I took a quick look at this last night and the only thing we really need is the addition of a set of rhashtable interfaces which use NULLs lists, as the inet hashtables currently require. Also, I noticed in the netlink changes this really expensive synchronize_net() added to netlink_release(), is that _really_ necessary? That's really expensive and my impression was that such a sync is only needed during hash table resizing, not when getting rid of objects that we in an rhashtable.
