Sorry, i still don't understand this.

If i do a normal read() on a Trivfs translator, trivfs_S_io_read in my
translator gets called. OK. But, in the read() call, i haven't
specified a datalen. Now, at which point does this datalen parameter
get "created"?

I guess, it's a quiet silly question. I just don't understand yet how
all these things interact with each other..

Bye,
