I'll submit a patch to get rid of that shortly. I think your patch is fine because the 'no timer in ecache extension' change is quite large, needs review/stress testing etc and is inapropriate for stable tree anyway. > I have seen "len" up to 280 and my host has crashes w/o this patch. ecache is 24 bytes without that timer, should be < 256 in total for all extensions. I think BUILD_BUG_ON test would be nice. -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
