类型参数名称
const union fscrypt_policy *policy
92  当:version恒等于Legacy policy version; ad-hoc KDF and no key verification.* For new encrypted directories, use fscrypt_policy_v2 instead.* Careful: the .version field for this is actually 0, not 1.
93  返回:v1的长度
94  当:version恒等于New policy version with HKDF and key verification (recommended).
95  返回:v2的长度
97  返回:0
