  "message": "throttle: Check current timers before updating any_timer_armed[]\n\nCalling throttle_group_config() cancels all timers from a particular\nBlockDriverState, so any_timer_armed[] should be updated accordingly.\n\nHowever, with the current code it may happen that a timer is armed in\na different BlockDriverState from the same group, so any_timer_armed[]\nwould be set to false in a situation where there is still a timer\narmed.\n\nThe consequence is that we might end up with two timers armed. This\nshould not have any noticeable impact however, since all accesses to\nthe ThrottleGroup are protected by a lock, and the situation would\nbecome normal again shortly thereafter as soon as all timers have been\nfired.\n\nThe correct way to solve this is to check that we\u0027re actually\ncancelling a timer before updating any_timer_armed[].\n\nSigned-off-by: Alberto Garcia \u003cberto@igalia.com\u003e\nMessage-id: 1434382875-3998-1-git-send-email-berto@igalia.com\nSigned-off-by: Stefan Hajnoczi \u003cstefanha@redhat.com\u003e\n",
