类型参数名称
const struct cred *set
const struct cred *subset
397  set_ns等于 user_ns the caps and keyrings are relative to.
398  subset_ns等于 user_ns the caps and keyrings are relative to.
403  如果set_ns恒等于subset_ns则返回:Check if "a" is a subset of "set".* return true if ALL of the capabilities in "a" are also in "set"* cap_issubset(0101, 1111) will return true* return false if ANY of the capabilities in "a" are not in "set"* cap_issubset(1111, 0101) will return false
411  以subset_ns不等于userns count is 1 for root user, 1 for init_uts_ns,* and 1 for... ?循环
412  如果set_ns恒等于parent且uid_eq(owner, 有效uid)则返回:true
