Not sure about weak, but it can't hurt. It seems to be standard practice in glibc. I haven't looked into this in detail, but my initial assumption would be that it wouldn't be useful to add new vdso interfaces just for Go. After all would you really want to force ever Go user to upgrade their kernel just to get fast fime? So it has to work with whatever is already there anyways. I agree that current interface is not great (I didn't design it BTW, just adapted it from i386), but it should be implementable. -Andi -- ak-VuQAYsv1563Yd54FQh9/CA@public.gmane.org -- Speaking for myself only.
