Ahh, I ended up not expecting you to get this done until after rc1 was out, so I in the meantime just merged my fix instead rather than leave the expected scheduling-while-atomic problem. And just as well that you did a baseline, since apparently the numbers are all over the map. I don't see how your hack and dave's original can _possibly_ differ that much, but they clearly did on your xfs test. So there's probably huge variance that depends on random details. I'll leave things as they are until we have something that looks a bit more believable ;) Linus -- 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
