From 0497fb6090d1ed34ac1bdcaaff49847025d13e9e Mon Sep 17 00:00:00 2001 From: anand Date: Mon, 8 Jun 2015 00:19:00 +0530 Subject: glusterd: Get the local txn_info based on trans_id in op_sm call backs. Issue: when two or more transactions are running concurrently in op_sm, global op_info might get corrupted. Fix: Get local txn_info based on trans_id instead of using global txn_info for commands (re-balance, profile ) which are using op_sm in originator. TODO: Handle errors properly in call backs and completely remove the global op_info from op_sm.
