            Bug ID: 1233258
           Summary: Possible double execution of the state machine for
                    fops that start other subfops
           Product: GlusterFS
           Version: mainline
         Component: disperse
          Assignee: bugs at gluster.org

Description of problem:

When a fop starts a subfop as part of its own execution, it's possible that
this subfop finishes before the manager has completed the processing of the
current state. In this case ec_resume() is called and a new instance of the
same state machine is executed by another thread.

This could cause multiple problems.
