Yes, but not in this patchset. The current code is already so, therefore needs a different patchset. Quite contrarily, my patchset actually improves it _a little bit_ by moving the second rcu_barrier() in current code base to a workqueue... The contention is same, just that we no longer block tcf_block_put() path with my patchset.
