Subject: [PATCH RFC tip/core/rcu 0/2] RCU consolidation patches

---

Hello!

This series is a sneak preview of a pair of patches that does the actual
consolidation of RCU-bh and RCU-sched functionality into RCU-preempt.
This does pass some light rcutorture testing, but left unattended will
no doubt do unspeakable things to your pets, your loved ones, and your
household devices. Once fully debugged, this patch set will be followed
up with a cleanup series that actually removes RCU-bh and RCU-sched.
In the meantime:

1. Make RCU-preempt treat disabling of interrupts, preemption,
and/or softirq as read-side critical sections. Most of the
complexity deals with composite read-side critical sections in
which sometimes preemption is disabled, other times there is an
rcu_read_lock() in force, yet other times interrupts are disabled,
and so on.

2. Make the "rcu" torture type create composite read-side critical
sections in order to test #1 above.

There is some faint hope of these going into the next merge window,
but it is far more likely that bug fixing will take longer than that,
pushing them into the merge window following the next one. Furthermore,
without the cleanup patches, the actual goal of having only one flavor
of RCU is not met. Besides, given the large number of patches already
slated for the next merge window, deferring any additional patches might
not be such a bad idea anyway.

Thanx, Paul

Subject: [PATCH RFC tip/core/rcu 1/2] rcu: Defer reporting RCU-preempt quiescent states when disabled

---

This commit defers reporting of RCU-preempt quiescent states at
rcu_read_unlock_special() time when any of interrupts, softirq, or
preemption are disabled. These deferred quiescent states are reported
at a later RCU_SOFTIRQ, context switch, idle entry, or CPU-hotplug
offline operation. Of course, if another RCU read-side critical
section has started in the meantime, the reporting of the quiescent
state will be further deferred.

This also means that disabling preemption, interrupts, and/or
softirqs will act as an RCU-preempt read-side critical section.
This is enforced by checking preempt_count() as needed.

Some special cases must be handled on an ad-hoc basis, for example,
context switch is a quiescent state even though both the scheduler and
do_exit() disable preemption. In these cases, additional calls to
rcu_preempt_deferred_qs() override the preemption disabling. Similar
logic overrides disabled interrupts in rcu_preempt_check_callbacks()
because in this case the quiescent state happened just before the
corresponding scheduling-clock interrupt.

This change lifts a long-standing restriction that required that if
interrupts were disabled across a call to rcu_read_unlock() that the
matching rcu_read_lock() also be contained within that interrupts-disabled
region of code. Because the reporting of the corresponding RCU-preempt
quiescent state is now deferred until after interrupts have been enabled,
it is no longer possible for this situation to result in deadlocks
involving the scheduler's runqueue and priority-inheritance locks.
This may allow some code simplification that might reduce interrupt
latency a bit. Unfortunately, this would also defer deboosting a
low-priority task that had been subjected to RCU priority boosting,
so real-time-response considerations might well force this restriction
to remain in place.

Because RCU-preempt grace periods are now blocked not only by RCU
read-side critical sections, but also by disabling of interrupts,
preemption, and softirqs, it will be possible to eliminate RCU-bh and
RCU-sched in favor of RCU-preempt in CONFIG_PREEMPT=y kernels. This may
require some additional plumbing to provide the network denial-of-service
guarantees that have been traditionally provided by RCU-bh. Once these
are in place, CONFIG_PREEMPT=n kernels will be able to fold RCU-bh
into RCU-sched. This would mean that all kernels would have but
one flavor of RCU, which would open the door to significant code
cleanup.

Moving to a single flavor of RCU would also have the beneficial effect
of reducing the NOCB kthreads by at least a factor of two.

Subject: [PATCH RFC tip/core/rcu 2/2] rcutorture: Handle extended "rcu" read-side critical sections

---

This commit makes the "rcu" torture type test extended read-side
critical sections in order to test the deferral of RCU-preempt
quiescent-state testing.

In CONFIG_PREEMPT=n kernels, this simply duplicates the setup already
in place for the "sched" torture type.

Would it be better to just test for those bits just to be safe the higher
order bits don't bleed in, such as PREEMPT_NEED_RESCHED, something like the
following based on the 'dev' branch?

Hi Paul,

I had a similar idea of checking the preempt_count() sometime back but didn't
believe this path can be called with preempt enabled (for some reason ;-)).
Now that I've convinced myself that's possible, what do you think about
taking advantage of the opportunity to report a RCU-sched qs like below from
rcu_check_callbacks ?

Did some basic testing, can roll into a patch later if you're Ok with it.

thanks.

The problem here is that the code patch above cannot be called
with CONFIG_PREEMPT_COUNT=n, but the code below can. And if
CONFIG_PREEMPT_COUNT=n, the return value from preempt_count() can be
misleading.

Or am I missing something here?

That is true! so then I could also test if PREEMPT_RCU is enabled like you're
doing in the other path.

For more precision, s/PREEMPT_RCU/CONFIG_PREEMPT_COUNT/

Hmmm... I recently queued a patch that redefines the RCU-bh update-side
API in terms of the consolidated RCU implementation, so this "else"
clause no longer exists. One approach would be to fold this condition
(with the addition of SOFTIRQ_MASK) into the previous "if" condition,
but that would call rcu_note_voluntary_context_switch() at bad times.
So maybe this becomes a new "else if" clause.

Another complication is an upcoming step that redefines the RCU-sched
update-side API in terms of the consolidated RCU implementation, which
will likely restructure this "if" statement yet again.

So I will try to fold this idea in (with attribution). If I don't get
it in place in a week or two, please remind me. Of course, one good way
to remind me is to supply a patch against whatever this turns into. ;-)

Thanx, Paul

Sounds good, I will keep these complications in mind and remind you in some
time and/or supply a patch doing the same. Will continue going through the
new code in your tree and let you know anything I find.
