Merge branch 'tcp-2nd-listener-hash'
Martin KaFai Lau says: ==================== tcp: Add a 2nd listener hashtable (port+addr) This patch set adds a 2nd listener hashtable. It is to resolve the performance issue when a process is listening at many IP addresses with the same port (e.g. [IP1]:443, [IP2]:443... [IPN]:443) v2: - Move the new lhash2 and lhash2_mask before the existing listening_hash to avoid adding another cacheline to inet_hashinfo (Suggested by Eric Dumazet, Thanks!) - I take this chance to plug an existing 4 bytes hole while adding 'unsigned int lhash2_mask'. - Add some comments about lhash2 in inet_hashtables.h ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
