Sure, done for v4, along with the other three from this run: the rcu_read_unlock_tasks_trace() lockdep ordering in 02, the @regs kerneldoc in 01, and the Documentation wording in 13 now mentions the rcu_tasks_trampoline_text() / rcu_tasks_wait_irq_preempted() route the kprobe optimizer takes. The kerneldoc here no longer points at the sample header. The Fixes: suggestion doesn't apply, 03 and 05 are the same series and nothing selects the option until 13. Thanks, Josef
