dm verity: log the hash algorithm implementation Log the hash algorithm's driver name when a dm-verity target is created. This will help people determine whether the expected implementation is being used. It can make an enormous difference; e.g., SHA-256 on ARM can be 8x faster with the crypto extensions than without. It can also be useful to know if an implementation using an external crypto accelerator is being used instead of a software implementation. Example message: [ 35.281945] device-mapper: verity: sha256 using implementation "sha256-ce" We've already found the similar message in fs/crypto/keyinfo.c to be very useful.
