Whether it's redundant or not is a separate question - it very well might be, due to the code in ioctx_alloc() that caps nr_events, but that needs a proof. In any case, the reasons you are offering in commit message are wrong - it's about size being too _large_, not too small. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
