Maybe. But I still hope this is not necessary, the driver should be able to do at least primitive header splitting, in that case the header could be inlined to skb. Alternatively, header can be copied with skb_pull(). Not good, but it is at least a regula procedure, which f.e. allows to keep the pages in highmem. > What if we will store array of pages and in shared info > just like we have right now. So there will only one destructor. Seems, this is not enough. Actually, I was asking for your experience with aio. The simplest situation, which confuses me, translated to aio language: two senders send two pages. Those pages are to be recycled, when we are done. We have to notify both. And we have to merge both those pages in one segment. The second half of that mail suggested three different solutions, all of them creepy. :-) Alexey - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
