ecryptfs_initialize_file

Cause the file to be changed from a basic empty file to an ecryptfs file with a header and first data page.

Returns zero on success

ecryptfs_truncate : The ecryptfs layer dentry : The length to expand the file to

Simple function that handles the truncation of an eCryptfs inode and its corresponding lower inode.

Returns zero on success; non-zero otherwise
