Of course, one may write a special benchmark on a BIG SMP/NUMA machine that defeat these patch, using thousands of epoll ctl per second, but, a normal (well written ?) epoll application doesnt constantly add/remove epoll ctl. Should we waste 8 bytes per 'struct file' for a very unlikely micro benchmark ?
