Quoting Arnaldo Carvalho de Melo:
| struct dccp_tx_hist_entry {
| struct list_head dccphtx_node; /* 0 16 */
| u64 dccphtx_seqno; /* 16 8 */
| struct timeval dccphtx_tstamp; /* 24 16 */
| }; /* size: 40, cachelines: 1 */
| /* last cacheline: 40 bytes */
| [acme@mica net-2.6.22]$
|
| I wonder if we could make this a single linked list, lemme see.. I
| think so, and by doing that we get the struct down to 32 bytes, making
| it cacheline friendly, and also simplify the operations, i.e. that
| opencoded list operation would just go away, will leave this for
| later, in a TODO file.
This is an excellent idea - I have just checked. It works, there is no sorting
and just LIFO order.
Will you be working on this or would you like me to update this in terms of
struct hlist_head?
