kernel - dm_target_crypt - use CRYPTO_F_BATCH
* Allow crypto requests to be dispatched to multiple crypto support
threads instead of executing the operation synchronously.
* Greatly improves crypto performance on SMP boxes. 25MB/s -> 80MB/s on
my quad.
* Currently the ivgen code gets in the way because it must be executed
synchronously before the data crypto op can be initiated. Further
performance improvements are possible.
