Hi Evgeniy, You'll probably want to start by looking at my Linux Plumbers slides presenting rculfhash: https://www.efficios.com/lpc2011-urcu Also, Paul McKenney's slides of the Userspace RCU tutorial here present other numbers of a hash table example (including bucket-locks), AFAIK using his own statically sized hash table implementation (not rculfhash): https://events.linuxfoundation.org/sites/events/files/slides/userspace-rcu-tutorial-linuxcon-2013.pdf Thanks, Mathieu > -- > Cheers, > Evgeniy > > _______________________________________________ > lttng-dev mailing list > [email protected] > http://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev > -- Mathieu Desnoyers EfficiOS Inc. http://www.efficios.com _______________________________________________ lttng-dev mailing list [email protected] http://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
