fscrypt_key_describe
add_existing_master_key
do_remove_key	Try to remove an fscrypt master encryption key
fscrypt_ioctl_get_key_status	Retrieve the status of an fscrypt master encryption key
setup_file_encryption_key	Find the master key, then set up the inode's actual encryption key.* If the master key is found in the filesystem-level keyring, then the* corresponding 'struct key' is returned in master_key_ret with ->mk_secret_sem read-locked
fscrypt_drop_inode	scrypt_drop_inode - check whether the inode's master key has been removed* Filesystems supporting fscrypt must call this from their ->drop_inode()* method so that encrypted inodes are evicted as soon as they're no longer in
