For some reason I am not sure if removing the timeout from the stack is been a good idea.
My kernel is just running without tsk->timeout and using schedule_timeout() though. I can' t produce a patch right now because I need to clean tons of garbage and to do that I have to review all the patch (if you want the patch with the garbage ask and I' ll sent to you). If I boot with jiffies = 0 everything seems OK. If I boot with jiffies = -120*HZ and timer_jiffies = -120*HZ the timer code became messy (before and after the jiffies wrap). I don' t understand at all yet the details of the timer code, but it seems that I can' t choose a random jiffies value to start (I am complelty wrong on this?).
