[lustre-devel] [PATCH 09/13] lnet: socklnd: expect two control connections maximum

From: Serguei Smirnov <ssmirnov at whamcloud.com>

As a result of connecting to ourselves, e.g. pinging own nid,
two control type connections are established vs. just one
in case of connecting externally.
Fix the control connection counter to be able to handle that.
