This is not necessary, David already _did_ the thing, and _told_ so.


You probably missed fact we are in merge window, so fixes (and only fixes)
are pushed into net-2.6 tree.

When Linus closes this merge window (issuing a linux-2.6.33-rc1 tag),
then David re-opens net-next-2.6 tree for new stuff.

commit 3dc789320e1b310cb505dcd94512c279abcd5e1c

    tcp: Remove runtime check that can never be true.

    GCC even warns about it, as reported by Andrew Morton:

    net/ipv4/tcp.c: In function 'do_tcp_getsockopt':
    net/ipv4/tcp.c:2544: warning: comparison is always false due to limited range of data type
