At this point I'm afraid it's all lost in the mists of time, but the original patch seems to have come from http://lists.openfabrics.org/pipermail/general/2006-July/024322.html looking at the patch, I would guess that the corruption occurred when the target got an IO request that started at a non-page-aligned address but that spanned more than one page. I don't know if the target was ever fixed, or whether that target code has any relevance today. - R. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
