Hi Song, I'm having a bit of trouble reproducing this now. I'm going to drop this patch from the series for now and see if something changed in crypto layers or elsewhere. I originally saw this on a bit older kernel so something might changed. Feels a bit like a work-around anyways so I'll dig into it a bit more. Either way I'll try and understand this a bit better. Thanks for the question.
