 Inline encryption support
 =========================
 
-By default, fscrypt uses the kernel crypto API for all cryptographic
-operations (other than HKDF, which fscrypt partially implements
-itself).  The kernel crypto API supports hardware crypto accelerators,
-but only ones that work in the traditional way where all inputs and
-outputs (e.g. plaintexts and ciphertexts) are in memory.  fscrypt can
-take advantage of such hardware, but the traditional acceleration
-model isn't particularly efficient and fscrypt hasn't been optimized
-for it.
-
-Instead, many newer systems (especially mobile SoCs) have *inline
-encryption hardware* that can encrypt/decrypt data while it is on its
-way to/from the storage device.  Linux supports inline encryption
-through a set of extensions to the block layer called *blk-crypto*.
-blk-crypto allows filesystems to attach encryption contexts to bios
-(I/O requests) to specify how the data will be encrypted or decrypted
-in-line.  For more information about blk-crypto, see
