This isn't a bug, but could the field and ftrace_direct_mark_module()'s
body be gated on CONFIG_TASKS_RCU_TRAMPOLINE_READERS instead?
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
