| |
arch_reinit_sched_domains used to call arch_update_cpu_topology via arch_init_sched_domains. This call got lost with e761b7725234276a802322549cee5255305a0930 ("cpu hotplug, sched: Introduce cpu_active_map and redo sched domain managment (take 2)".
So we might end up with outdated and missing cpus in the cpu core maps (architecture used to call arch_reinit_sched_domains if cpu topology changed).
This patch set changes arch_update_cpu_topology so that it can indicate if the cpu topology changed and adds a call to arch_update_cpu_topology in partition_sched_domains which gets called whenever scheduling domains get updated. Which is what is supposed to happen when cpu topology changes.
