Was anything done about size/member alignment of struct tcp_sock per
mail from last year  -
http://marc.theaimsgroup.com/?l=linux-netdev&m=114318857102290&w=2

(I have no idea what current size is)

Nothing has been done yet but I've been thinking about it a lot
over the past year and I've had some discussions with other
developers such as Arnaldo.

It's just a matter of me being backlogged, so I never get to
it as often as I would like :)

Attached goes a current (DaveM's net-2.6 git tree build) pahole
picture of tcp_sock on UP, 32bits, summary:

}; /* size: 1288, cachelines: 21 */
   /* last cacheline: 8 bytes */

and for the really curious, take a look at:

http://oops.ghostprotocols.net:81/acme/dwarves/tcp_sock.pahole.expand_types.txt

All the types are expanded, makes a pretty big picture :-)
