+Subject: [PATCH] Support changed libxenctrl API in Xen 4.18.0
+
+The xc_domain_getinfo() is gone, it's replaced with
+xc_domain_getinfo_single. While the new API is a bit nicer, xenctrl.h
+does not provide any #define to know which one is available. Check
+library version in the makefile for that.
