Hi Kris,
you're quite right but: former what I mean to say is that the problem *exists*.
Nobody can write a syscall with more than 8 arguments and this is conceptually
wrong. In my opinion this is a mistake, no assumptions might be done on
number of arguments (I've not seen a documentation about that somewhere
too...). Latter, it could be a security problem. I've seen a lot of bug
declared *not exploitable* exploitted by other coders after some times.
Nothing is impossible. I wanted to point out that. I think this is different
respect VFS pointers, don't you agree?
