Agree. I thought of something that could be particularly related to the aio implementation; but I guess there's nothing so special then.
[snip] It probably makes sense to implement per-user limits rather than the current global limit, and maybe even convert them to an rlimit to better fit in with the available frameworks for managing these things.
I see it would be a nice improvement, but unfortunately that's not a task that I can take at the moment. For now, the most I'm able to do is to continue to try to understand whether there's something we can do that may help the small nr_events case to be more on par with the large nr_events case.. or any other beginner-level fixes to the area. :) Thanks again, -- Mauricio Faria de Oliveira IBM Linux Technology Center -- 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
