The same build in Xenial works, so comparing

on both its seen that Xenial version is smaller (Apr 9), and Stretch has a larger version (Apr 14).

The Stretch version of /usr/include/linux/fs.h now has the same structs as xfs.h, so we get the redefinition errors.

I saw no patch of the Xen tools tree to fix this, so I searched the qemu-xen configure for a switch.


turned up this flag: --disable-xfsctl
--with-extra-qemuu-configure-args="--disable-werror --disable-xfsctl"

the build now works.
