Subject: [TCP]: Use old definition of before
X-Git-Tag: v2.6.20-rc4~85^2~1
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0d630cc0a6cb8ad544b5913a26ff1349ed7c8587;p=linux-2.6

[TCP]: Use old definition of before

This reverts the new (unambiguous) definition of the TCP `before'
relation. As pointed out in an example by Herbert Xu, there is
existing code which implicitly requires the old definition in order
to work correctly.
