spinlock per entry is usually overkill for larger hash tables. Can you use a second smaller lock table that just has locks and is indexed by a subset of the hash key. Most likely a very small table is good enough. Also I would be good to have some data on the additional memory consumption. -Andi -- [email protected] -- Speaking for myself only -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
