From: Eric Biggers <[email protected]> bio_crypt_set_ctx(), blk_crypto_init_key(), and blk_crypto_start_using_key() are needed to use inline encryption; see Documentation/block/inline-encryption.rst. Export them so that dm-inlinecrypt can use them. The only reason these weren't exported before was that inline encryption was previously used only by fs/crypto/ which is built-in code.
