workqueue_set_unbound_cpumaskworkqueue_set_unbound_cpumask - Set the low-level unbound cpumask*@cpumask: the cpumask to set* The low-level workqueues cpumask is a global cpumask that limits* the affinity of all unbound workqueues. This function check the @cpumask
workqueue_init_earlyworkqueue_init_early - early init for workqueue subsystem* This is the first half of two-staged workqueue subsystem initialization* and invoked as soon as the bare basics - memory allocation, cpumasks and* idr are up
sched_setaffinity
build_group_from_child_sched_domainXXX: This creates per-node group entries; since the load-balancer will* immediately access remote memory to construct this group's load-balance* statistics having the groups node local is of dubious benefit.

guarantee_online_cpusReturn in pmask the portion of a cpusets's cpus_allowed that* are online. If none are online, walk up the cpuset hierarchy* until we find one that does have some online cpus.* One way or another, we guarantee to return some non-empty subset
