Oh, nice. Missed that.

Yes, it's a requirement for upstreaming and I suspect it's the reason
why the vendor (Altera) is taking so long to mainline this. They're
probably not happy
with breaking the current userspace compatibility.

Well, I can understand this. Although it might mean you'll never merge it :-(
I've no idea about Altera's plans and I don't have enough time to take
care of the whole upstreaming on my own (at least in the near future).
Since I use strace as a valuable debugging tool, guess I'll carry this
patch around. Still it would be wonderful to have it merged.
So let me ask you to consider this twice :-)
Moreover, as Mike says, maybe the only thing we'll have to change is
the syscall array.
