Now, looking at it in the stable/9 context, I can see that pjd did not merge (as he said at the time of commit) r226839 & r226839.

My patch would only effect userland applications that use /dev/crypto... If they do their own AES-NI work, then there isn't any improvement... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."Received on Fri Aug 23 2013 - 16:05:14 UTC
