I think the latter. For this commit I think the patch for master branch was 
picked
for the 4.13-4.15 backporting, without noticing the xc_shadow_control()
prototype change in 4.16.

I can send a fix for this. If we don't want to backport the
"libxc: split xc_logdirty_control() from xc_shadow_control()"

Kind regards,
Henry
