> 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 Nice work, series applied.
