[Xen-devel] is_initial_xendomain()

["Jan Beulich" <jbeulich@xxxxxxxxxx>]

Seeing many cases of uses like

#ifdef CONFIG_XEN_PRIVILEGED_GUEST
        if (is_initial_xendomain()) {
                ...
        }
#endif

I'm wondering if it wasn't nice to eliminate the preprocessor
conditionals (which appear to be there only to cut down on
code size) by doing the conditional in a single place instead:

#ifdef CONFIG_XEN_PRIVILEGED_GUEST
#define is_initial_xendomain() (xen_start_info->flags & SIF_INITDOMAIN)
#else
#define is_initial_xendomain() 0
#endif

If that is acceptable, I'm ready to create a respective patch
(but I'd like to avoid spending time on it if there are objections).

Jan
