Eric Biggers f4f864c121 fscrypt: add a documentation file for filesystem-level encryption ... Perhaps long overdue, add a documentation file for filesystem-level encryption, a.k.a. fscrypt or fs/crypto/, to the Documentation directory. The new file is based loosely on the latest version of the "EXT4 Encryption Design Document (public version)" Google Doc, but with many improvements made, including: - Reflect the reality that it is not specific to ext4 anymore. - More thoroughly document the design and user-visible API/behavior. - Replace outdated information, such as the outdated explanation of how encrypted filenames are hashed for indexed directories and how encrypted filenames are presented to userspace without the key. (This was changed just before release.) For now the focus is on the design and user-visible API/behavior, not on how to add encryption support to a filesystem --- since the internal API is still pretty messy and any standalone documentation for it would become outdated as things get refactored over time.
