I wonder whether > that would be better moved into xen_common.h too (since it's just a > wrapper round xc_set_hvm_param() and then the inclusion of params.h > can be moved there as well. :(, I didn't realised that xen_common.h needed params.h too. That patch series might not build on older version of Xen. I'll move the inclusion of params.h to xen_common.h, and fix params.h to have all the needed #defines. About xen_suspend_notifier(), it's actually more than a wrapper, it's also a function. A pointer to the function is given to a notifier. So I don't think using "inline" will work, and I don't think it makes sense to have a function without "inline" in xen_common.h. So I think xen_{suspend,wakeup}_notifier are fine where there are, do you agree? Thanks, -- Anthony PERARD
