Gilad Ben-Yossef d1ac3ff008 dm verity: switch to using asynchronous hash crypto API ... Use of the synchronous digest API limits dm-verity to using pure CPU based algorithm providers and rules out the use of off CPU algorithm providers which are normally asynchronous by nature, potentially freeing CPU cycles. This can reduce performance per Watt in situations such as during boot time when a lot of concurrent file accesses are made to the protected volume.
