[Cluster-devel] [PATCH] rgmanager: Fix short read handling while loading resource rules

[Lon Hohberger]

If a short read occurs (maybe due to a race between the parent/child
processes in SMP systems?) while reading from the pipe while using
resource rules, we break the loop early even if there's more data to be
had at a later time.

It fixed the problem for the reporter.
