Name:pumask_equal - *src1p == *src2p*@src1p: the first input*@src2p: the second input

Proto:static inline bool cpumask_equal(const struct cpumask *src1p, const struct cpumask *src2p)

Type:bool

Parameter:

TypeParameterName
const struct cpumask *src1p
const struct cpumask *src2p
488  Return bitmap_equal(cpumask_bits - get the bits in a cpumask*@maskp: the struct cpumask ** You should only assume nr_cpu_ids bits of this mask are valid. This is* a macro so it's const-correct.(src1p), cpumask_bits - get the bits in a cpumask*@maskp: the struct cpumask ** You should only assume nr_cpu_ids bits of this mask are valid. This is* a macro so it's const-correct.(src2p), nr_cpumask_bits)

wqattrs_equalent equality test
wq_calc_node_cpumaskwq_calc_node_cpumask - calculate a wq_attrs' cpumask for the specified node*@attrs: the wq_attrs of the default pwq of the target workqueue*@node: the target NUMA node*@cpu_going_down: if >= 0, the CPU to consider as offline*@cpumask: outarg, the
wq_update_unbound_numawq_update_unbound_numa - update NUMA affinity of a wq for CPU hot[un]plug*@wq: the target workqueue*@cpu: the CPU coming up or going down*@online: whether @cpu is coming up or going down* This function is to be called from %CPU_DOWN_PREPARE, %CPU_ONLINE
sd_parent_degenerate
build_balance_maskBuild the balance mask; it contains only those CPUs that can arrive at this* group and should be considered to continue balancing
init_overlap_sched_group
topology_span_saneEnsure topology masks are sane, i.e. there are no conflicts (overlaps) for* any two given CPUs at this (non-NUMA) topology level.
build_sched_domainsBuild sched domains for a given set of CPUs and attach the sched domains* to the individual CPUs
partition_sched_domains_lockedPartition sched domains as specified by the 'ndoms_new'* cpumasks in the array doms_new[] of cpumasks. This compares* doms_new[] to the current sched domain partitioning, doms_cur[].* It destroys each deleted domain and builds each new domain.
