posix: In brick_mux brick is crashed while start/stop volume in loop
Problem: In brick_mux environment sometime brick is crashed while volume stop/start in a loop.Brick is crashed in janitor task at the time of accessing priv.If posix priv is cleaned up before call janitor task then janitor task is crashed. Solution: To avoid the crash in brick_mux environment introduce a new flag janitor_task_stop in posix_private and before send CHILD_DOWN event wait for update the flag by janitor_task_done Change-Id: Id9fa5d183a463b2b682774ab5cb9868357d139a4 fixes: bz#1730409 Signed-off-by: Mohit Agrawal <moagrawal@redhat.com>
