The syntax-check rule in 27/27 should cover this - it will complain if
we introduce a 'int flags;' in any of the *protocol.x files, which
should prod us to use 'unsigned int flags;' instead.

Or are you referring to the fact that patch 27/27 only checked
libvirt.h.in for additions of '...long flags', to ensure that no more
than the existing 4 uses for migration are added?  In that case, yeah,
that rule can be enhanced to check include/libvirt/libvirt-qemu.h as
well, to ensure that all new public APIs, whether for libvirt proper or
for libvirt-qemu, use 'unsigned int flags'.  But that's a tweak to 27,
not to this one, so I pushed 4/27 as-is.
