Linus Torvalds aba9da0905 RCU fixes for v7.0 - Part 2
Fix a regression introduced by commit c27cea4416 ("rcu: Re-implement
 RCU Tasks Trace in terms of SRCU-fast"): BPF contexts can run with
 preemption disabled or scheduler locks held, so call_srcu() must work in
 all such contexts. Fix this by converting SRCU's spinlocks to raw
 spinlocks and avoiding scheduler lock acquisition in call_srcu() by
 deferring to an irq_work (similar to call_rcu_tasks_generic()), for both
 tree SRCU and tiny SRCU. Also fix a follow-on lockdep splat caused by
 srcu_node allocation under the newly introduced raw spinlock by
 deferring the allocation to grace-period worker context.

  srcu: Use irq_work to start GP in tiny SRCU
  rcu: Use an intermediate irq_work to start process_srcu()
  srcu: Push srcu_node allocation to GP when non-preemptible
  srcu: Use raw spinlocks so call_srcu() can be used under preempt_disable()
