I said that because the structure that contains this buffer is now larger than a page, you should allocate the CB buffer externally via another kmalloc() or via the page allocator. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
