Subject: minios: Implement some extra lib functions for ocaml xenstored stubdom
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~13904
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=0e57a92cc388c377de3940d12ac6131c698f5581;p=xen.git

minios: Implement some extra lib functions for ocaml xenstored stubdom

We could stub them out as unsupported, but we may as well implement
them as they are very simple.
