Is the ( ... & epi->event.events) really necessary ? (It seems already done) I was wrong about the size of epitem : it is now 68 bytes instead of 72. At least we now use/dirty one cache line instead of two per epitem. Do you have another brilliant idea to shrink 4 more bytes ? :) It seems to me 'nwait' is only used at init time (so that ep_ptable_queue_proc() can signal an error occured). Maybe another mechanism could let us delete nwait from epitem ? We could use a field in task_struct for example (see usage of total_link_count for example) Thank you - 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/
