this isn't entirely correct I think. iser_finalize_rdma_unaligned_sg is called from a tasklist, which is softirq context, so you can't use KM_USER0 there. KM_SOFTIRQ0 should probably work. Otoh tasklets are not very scalable because tasklets of a type a serialized against running at multiple cpus, so maybe you should switch to a different mechanisms. _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
