From: Eric Biggers <ebiggers@xxxxxxxxxx> FS_IOC_GET_ENCRYPTION_POLICY_EX allows filesystem encryption users to retrieve the encryption policy for files and directories that use a v2 encryption policy. Unlike the original FS_IOC_GET_ENCRYPTION_POLICY, FS_IOC_GET_ENCRYPTION_POLICY_EX is also extensible to new versions of the policy struct that may be added in the future.
