Did you want pointer for timeout in the userspace api?  I don't feel strongly about it, I just didn't see a use.  The equivalent API I could think of was select(), where apparently linux returns time unwaited, while "everyone else" doesn't.  I don't see a strong recommendation either way from that.

I wanted the kernel to return the unwaited time (or at least a upper bound to it, with coarse clocks that's the best we can do) so that ioctl restarting after a signal does the right thing. Exposing that any further than libdrm doesn't make much sense imo. -Daniel
