Name:pumask_subset - (*src1p & ~*src2p) == 0*@src1p: the first input*@src2p: the second input* Returns 1 if *@src1p is a subset of *@src2p, else returns 0

Proto:static inline int cpumask_subset(const struct cpumask *src1p, const struct cpumask *src2p)

Type:int

Parameter:

TypeParameterName
const struct cpumask *src1p
