The problem is, purely my opinion, how many more we should add? This
doesn't mean I am trying to offend your idea, Manish. In fact, if we
have "plenty of room" for errno and user space can adapt such a fast
change, maybe that won't be a problem.
This kind of problem is similar to question: should it become syscall
or not? Should we change existing syscall parameters composition or
not? This might or might not introduce new problem.
My take on this situation: fix user space application so it can
"interpret" the real reason why a trouble happened. OK, it might cause
more headache....but this way we don't need to push libc and/or kernel
to adapt...which is...as you know....hard to dictate the way we
wanted.
Over all, this is just my opinion, so you may agree or disagree with it.

Mulyadi.
