build_merkle_tree	Build the Merkle tree for the given inode using the given parameters, and* return the root hash in @root_hash.* The tree is written to a filesystem-specific location as determined by the* ->write_merkle_tree_block() method
fsverity_ioctl_measure	sverity_ioctl_measure() - get a verity file's measurement* Retrieve the file measurement that the kernel is enforcing for reads from a* verity file
fsverity_init_merkle_tree_params	sverity_init_merkle_tree_params() - initialize Merkle tree parameters@params: the parameters struct to initialize@inode: the inode for which the Merkle tree is being built@hash_algorithm: number of hash algorithm to use@log_blocksize: log base 2 of

load_misc_binary	he loader itself
create_entry	This registers a new binary format, it recognises the syntax* ':name:type:offset:magic:mask:interpreter:flags'* where the ':' is the IFS, that can be chosen with the first char
create_elf_tables
load_elf_fdpic_binary	load an fdpic binary into various bits of memory
load_flat_binary	These are the functions used to load flat style executables and shared* libraries. There is no binary dependent code anywhere else.

ramfs_nommu_expand_for_mapping	add a contiguous set of pages into a ramfs inode when it's truncated from* size 0 on the assumption that it's going to be used for an mmap of shared* memory
netlbl_secattr_init	lbl_secattr_init - Initialize a netlbl_lsm_secattr struct@secattr: the struct to initialize Description:* Initialize an already allocated netlbl_lsm_secattr struct.
dccp_zeroed_hdr
smk_ad_init	some inline functions to set up audit data* they do nothing if CONFIG_AUDIT is not set

fscrypt_prepare_lookup	scrypt_prepare_lookup - prepare to lookup a name in a possibly-encrypted directory@dir: directory being searched@dentry: filename being looked up@fname: (output) the name to use to search the on-disk directory Prepare for ->lookup() in a directory
cdev_init	dev_init() - initialize a cdev structure@cdev: the structure to initialize@fops: the file_operations for this device* Initializes @cdev, remembering @fops, making it ready to add to the* system with cdev_add().
fscrypt_new_context_from_policy	scrypt_new_context_from_policy - create a new fscrypt_context from a policy* Create an fscrypt_context for an inode that is being assigned the given* encryption policy. A new nonce is randomly generated.* Return: the size of the new context in bytes.
fscrypt_policy_from_context	scrypt_policy_from_context - convert an fscrypt_context to an fscrypt_policy* Given an fscrypt_context, build the corresponding fscrypt_policy.* Return: 0 on success, or -EINVAL if the fscrypt_context has an unrecognized* version number or size.
