Hi Friends, I have a question about tasklets:
I understand that they are used to defer work during interrupt handling. What I don't understand is - how do they handle queuing of deferred work? Specially with tasklets, if a tasklet is re-scheduled before the previous scheduling of the same tasklet has a chance to run, then the tasklet is executed only once - not twice. But what if the work that the tasklet was supposed to do in these 2 instances were different and that its function was supposed to be passed 2 different structures? Shouldn't the tasklet be executed twice with these 2 structures? I know that work queues are there for that, but how do device drivers that use tasklets cope with the above?
