That means we need both the anon_vma locks and the i_mmap_lock to become semaphores. I think semaphores are better than mutexes. Rik and Lee saw some performance improvements because list can be traversed in parallel when the anon_vma lock is switched to be a rw lock. Sounds like we get to a conceptually clean version here? _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
