This will be useful for: 1. Evicting the inodes when a fscrypt key is removed, since we'll track the inodes using a given key by linking their fscrypt_infos together, rather than the inodes directly. This avoids bloating 'struct inode' with a new list_head. 2. Simplifying the per-file key setup, since the inode pointer won't have to be passed around everywhere just in case something goes wrong and it's needed for fscrypt_warn().
