One point I'm not sure about this implementation is the use of
tasklet. The tasklet itself runs again in ep->lock, what's the
rationale for it? In other words, can't it be a straight function
I would understand if it were a workqueue and running in the
schedulable context. But, I see no big merit of tasklet here.
(And tasklet is a candidate to be dropped sometime in future.)
Maybe I'm missing something behind it...
