I looked at ESSIV patch-set.
Can you please confirm that you mean:
'Register FMP as the template of skcipher instead of diskcipher,
and simplify the interface for FMP user'
If yes, I think the following API needs to be added to skcipher:
- _set(): BIO submitter (dm-crypt, f2fs, ext4) sets cipher to BIO.
- _mergeable(): Block layer checks if two BIOs have the same cipher.
- _get(): Storage driver gets cipher from BIO.
- _set_crypt(): Storage driver gets crypto information from cipher and
writes it on the descriptor of Storage controller.
Is it acceptable to skcipher ?
