Type:int

Parameter:

TypeParameterName
const struct cpuset *cs
233  Return st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from
Caller
NameDescribe
is_cpuset_subsets_cpuset_subset(p, q) - Is cpuset p a subset of cpuset q?* One cpuset is a subset of another if all its allowed CPUs and* Memory Nodes are a subset of the other, and its exclusive flags* are only set if the other's are set. Call holding cpuset_mutex.
validate_changevalidate_change() - Used to validate that any proposed cpuset change* follows the structural rules for cpusets
cpuset_read_u64
cpuset_css_online
nearest_hardwall_ancestorarest_hardwall_ancestor() - Returns the nearest mem_exclusive or* mem_hardwall ancestor to the specified cpuset. Call holding* callback_lock. If no ancestor is mem_exclusive or mem_hardwall* (an unusual configuration), then returns the root cpuset.
