If people don't like it, I'll drop it. I like the idea. I don't think it's immediately useful, since libraries wanting to use vdso will likely want to support older kernels that don't yet have this, and thus need to include their own vdso parsing code. However, if we could get this in now, it would be very useful a few years down the line where optimizing for old kernels is not an important goal. I'd certainly like to be able to drop the ELF parsing code from musl to reduce static binary size. And I could see other projects possibly using it just to avoid the issue of ever adding ELF parsing code in the first place.
