This patch series is based on Eric’s work posted at:
https://lore.kernel.org/all/ecbb7ea8-11f6-30c1-ad77-bd984c52ca33@quicinc.com/

Eric’s patches introduce a new dm target, dm-inlinecrypt, to support inline
block-device encryption. The implementation builds on the work previously done
in Android’s dm-default-key, but intentionally drops passthrough support,
as that functionality does not appear likely to be accepted upstream in the
near future. With this limitation, dm-inlinecrypt is positioned as a
practical replacement for dm-crypt, rather than a general passthrough
mechanism.

On top of Eric’s series, keyring key support is added in dm-inlinecrypt. Thus,
both keyring key and hex key are feasible for dm-inlinecrypt. In addition,
dm-inlinecrypt.rst is added as the user-guide of dm-inlinecrypt.
