#     Pull timer fix from Thomas Gleixner:
#      "A single timer fix:
#     
#        - Prevent a memory ordering issue in the timer expiry code which
#          makes it possible to observe falsely that the callback has been
#          executed already while that's not the case, which violates the
#          guarantee of del_timer_sync()"
