Documentation: Document the blk-crypto framework The blk-crypto framework adds support for inline encryption. There are numerous changes throughout the storage stack. This patch documents the main design choices in the block layer, the API presented to users of the block layer (like fscrypt or layered devices) and the API presented to drivers for adding support for inline encryption.

fscrypt: improve documentation for inline encryption Currently the fscrypt inline encryption support is documented in the "Implementation details" section, and it doesn't go into much detail. It's really more than just an "implementation detail" though, as there is a user-facing mount option. Also, hardware-wrapped key support (an upcoming feature) will depend on inline encryption and will affect the on-disk format; by definition that's not just an implementation detail. Therefore, move this documentation into its own section and expand it. Link: https://lore.kernel.org/r/20210916174928.65529-4-ebiggers@kernel.org Signed-off-by: Eric Biggers <ebiggers@google.com>
