Subject: MINOR: connection: add a new list member in the connection struct
X-Git-Tag: v1.6-dev4~116
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d75d40e9a8ef55a533742282854965b41f17ad3d;p=thirdparty%2Fhaproxy.git

MINOR: connection: add a new list member in the connection struct

This list member will be used to attach a connection to a list of
idle, reusable or queued connections. It's unused for now. Given
that it's not expected to be used more than a few times per session,
the member was put after the target, in the area starting at the
second cache line of the structure.
