This patchset contains some simplifications, bug fixes, documentation updates, and a bunch of leftover conversions to kfree_rcu(). Almost all of the latter need either an Acked-by or to be taken into the appropriate maintainer tree. The patches are as follows: 1. Simplify RCU kthread creation. 2. Convert from kthread_create() to kthread_create_on_node() (courtesy of Eric Dumazet). 3. Improve rcu_read_lock() code generation. 4. Restore checks for blocking within RCU read-side critical sections under CONFIG_PROVE_RCU. 5. Move struct rcu_head into types.h as a first step towards untangling header files. 6. Update rcutorture documentation to account for boosting, memory-barrier testing, and (not so) new flavors of RCU. 7. Fix type mismatch (courtesy of Andi Kleen). 8. Combine common grace-period-wait code. 9. Eliminate rcutorture workarounds for previously missing RCU API members, and add testing of synchronize_rcu_bh_expedited(). 10. Update RCU's NMI documentation. 11-27. Conversions to kfree_rcu() (courtesy of Lai Jiangshan, in need of either Acked-by or adoption). 28. Convert call_rcu(sk_filter_release_rcu) to kfree_rcu (courtesy of Lai Jiangshan, already acked).
