Nope, you cannot break the reordering I've done one month ago. http://git.kernel.org/?p=linux/kernel/git/davem/net-2.6.22.git;a=commit;h=1e19e02ca0c5e33ea73a25127dbe6c3b8fcaac4b [NET]: Reorder fields of struct dst_entry This last patch (but not least :) ) finally moves the next pointer at the end of struct dst_entry. This permits to perform route cache lookups with a minimal cost of one cache line per entry, instead of two. Both 32bits and 64bits platforms benefit from this new layout. - 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
