Hi Andi You wrote the original dm-crypt paralllelization patch (commit c029772125594e31eb1a5ad9e0913724ed9891f2). This patch improves parallelization, it makes data being encrypted on the same CPU that submitted the request. I improved that so that encryption is performed by all processors, it uses unbound workqueue, so that any processor can do encryption. My patches improves performance mainly when doing sequential read - your original patch paralellized sequential read badly because most requests were submitted by the same cpu. I put my patch series at http://people.redhat.com/mpatocka/patches/kernel/dm-crypt-paralelizace/current/series.html I'd like if you could look at it and ack it for inclusion in the upstream kernel.
