generate_sched_domains() returns sched-domain masks and optional attributes that are normally handed to partition_sched_domains(), which takes ownership of them. rebuild_sched_domains_locked() has a WARN guard after generate_sched_domains() and before partition_sched_domains() to avoid passing offline CPUs into the scheduler domain rebuild path. If that guard fires, the function currently returns directly without freeing the generated doms and attr. Free the generated sched-domain masks and attributes before returning from the guard failure path.
