    MD: Add del_timer_sync to mddev_suspend (fix nasty panic) · 0d9f4f13

    Use del_timer_sync to remove timer before mddev_suspend finishes.
    
    We don't want a timer going off after an mddev_suspend is called.  This is
    especially true with device-mapper, since it can call the destructor function
    immediately following a suspend.  This results in the removal (kfree) of the
    structures upon which the timer depends - resulting in a very ugly panic.
    Therefore, we add a del_timer_sync to mddev_suspend to prevent this.
