Andres -- should you have an entry in MAINTAINERS for this code?

I manipulated memshr as a side-effect of hypervisor/x86/mem_sharing. It's not my "baby" per se.
I think it'd be more appropriate for me to maintain hypervisor/x86/mem_sharing, and if so, I can take a stab at tools/memshr as well.
Of course, that discussion would involve Tim D (cc) and possibly others.
Thanks
Andres

The best way to kick it off would be with a patch to MAINTAINERS I
think.
Ian.
