In order to avoid build_free_nid lock contention, let's change the order of function calls as follows. At first, check whether there is enough free nids. - If available, just get a free nid with spin_lock without any overhead. - Otherwise, conduct build_free_nids. : scan nat pages, journal nat entries, and nat cache entries. We should consider carefullly not to serve free nids intermediately made by build_free_nids. We can get stable free nids only after build_free_nids is done.
