That's only going to happen in the next patch, though, right? It wouldn't hurt to write that in the changelog too. Besides, I'm not actually sure if starting/stopping the kthread in sugov_policy_alloc/free() is a good idea. It sort of conflates the allocation of memory with kthread creation. Any chance to untangle that? Thanks, Rafael
