Don't worry about this too much, I can always retest and resubmit, as long as the main idea is agreeable to you. My users are on RHEL. Therefore, my main concern is to get something into your tree in order to avoid this regressing in the future. Meanwhile, users of our 2.6.9 and 2.6.18 forks get a version of this patch. -- Pete - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
