Subject: [PATCH 159/169] glusterd: add an op-version check
Problem: "gluster v status" is hung in heterogenous cluster
when issued from a non-upgraded node.
Cause: commit 34e010d64 fixes the txn-opinfo mem leak
in op-sm framework by not setting the txn-opinfo if some
conditions are true. When vol status is issued from a
non-upgraded node, command is hanging in its upgraded peer
as the upgraded node setting the txn-opinfo based on new
conditions where as non-upgraded nodes are following diff
conditions.
Fix: Add an op-version check, so that all the nodes follow
same set of conditions to set txn-opinfo.
