[PATCH -tip 0/2] Temporary RCU fixes for notrace and hotplug CPU

[Paul E. McKenney]

This patchset adds a couple of needed "notrace" declarations and one
of two needed CPU-hotplug rcutree plugins.  This applies on top of
current tip/core/rcu, but is a temporary fix.  The problem with it is
that it is not bisectable when using ftrace.

This will be replaced with a later rework of the tip/core/rcu patch
stack.

[PATCH -tip 1/2] Add "notrace" to RCU function headers used by ftrace.

[Paul E. McKenney]

Both rcu_read_lock_sched_notrace() and rcu_read_unlock_sched_notrace()
are used by ftrace, and thus need to be marked "notrace".  Unfortunately,
my naive assumption that gcc would see the inner "notrace" does not hold.
Kudos to Lai Jiangshan for noting this.

Funny, inlines should not be traced. Is gcc ignoring the inlines here?

inline is just a hint. __attribute__((always_inline)) should be used to
really really forbid gcc to generate any function call. So notrace is
needed to make sure we do not trace such function call.

It reminds me of the old mkraid option --really-really-force (or
something like that). ;)

Well, that was my line of thinking as well, until Lai Jiangshan set
me straight.  Version 4.x of gcc apparently decides on a case-by-case
basis.

Yeah, I've seen gcc do it, but when it does it to static inlines in header 
files, I just get a feeling to squinge.

[PATCH -tip 2/2] Add CPU-offline processing for single-node configurations

[Paul E. McKenney]

From: Paul E. McKenney <paulmck@linux.vnet.ibm.com>

Add preemptable-RCU plugin to handle the CPU-offline processing.
An additional plugin is forthcoming to handle multinode RCU trees, but
this current plugin works for configurations up to 32 CPUs (64 CPUs for
64-bit kernels).

Re: [PATCH -tip 0/2] Temporary RCU fixes for notrace and hotplug CPU

[Ingo Molnar]

FYI, -tip testing found a new build warning on SH caused by the RCU 
tree (i suspect this warning triggers on other architectures as 
well):

/home/mingo/tip/kernel/rcutree.c:88: warning: '__rcu_offline_cpu' 
declared 'static' but never defined

it's harmless, but since we are generally trying to fix all warnings 
and gravitate towards more and more -Werror subsystems, it would be 
nice to fix this.

btw., i'm still seeing crashes with the latest RCU bits:

[   20.621740] Testing event sys_enter_futex: OK
[   20.629738] Testing event sys_exit_futex: OK
[   20.637737] Testing event lock_acquire: [reboot]

Possibly due to infinite recursion as well. Config attached.

Color me confused...

Unless someone has a better idea, I will send in a patch that adds
"notrace" to every RCU API member used by any file in the kernel
that has "trace" in its name (excluding ptrace.c and rcutree_trace.c,
of course).  This list is as follows:

	call_rcu()
	call_rcu_sched()
	rcu_read_lock()
	rcu_read_unlock()

So, any better ideas?

							Thanx, Paul

Tracers using RCU should use the _notrace() version of read_lock/unlock.
I think the callers should be fixed rather than RCU.

Tracepoints have been designed to use the _notrace variant on the
instrumentation site. The core of tracepoint management use
call_rcu_sched(), which can be traced without any problem.

I have not followed the late tracing development as closely though, so
errors might have crept in.

Or I might have inadvertently broken something in a non-obvious (to me,
anyway) manner.

So, would you be willing to look at commit bc33f24bd in the -tip
tree and see if there is anything I broke other than the now-fixed
rcu_read_lock_sched_notrace() and rcu_read_unlock_sched_notrace()?
And for that matter, whether my alleged fix for these two API members
really does fix the problem (-tip commit 7c614d6461)?

The -tip tree is at:

	git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git

And these patches are on the tip/core/rcu branch.

							Thanx, Paul

sure, here we go:

 static inline void rcu_read_lock_sched_notrace(void)
 {
        preempt_disable_notrace();
+       __acquire(RCU_SCHED);
+       rcu_read_acquire();
 }
 
and


 static inline void rcu_read_unlock_sched_notrace(void)
 {
+       rcu_read_release();
+       __release(RCU_SCHED);
        preempt_enable_notrace();
 }

will make those _notrace primitives call into lockdep. I don't think
this is correct, and this might be causing your problem.

rcu_read_acquire/release are calling lock_acquire/release, those should
be removed.

__acquire() simply seems to be defined to a gcc "context" attribute,
probably for the sparse checker. I think it should be safe to leave them
there.

Thank you for looking this over, Mathieu!!!  Please see below for patch.

Remove lockdep annotations from RCU's _notrace() API members.

The lockdep annotations rcu_read_acquire() and rcu_read_release()
might lead to infinite looping if called from lockdep.  So this patch
removes them.

Ah!!!  I understood the "add notrace" suggestion, but was confused into
thinking that "notrace" was going to prevent it from being called the
second time.

Indeed, and I have updated my build-output-check script to alert me to
warning messages from my multiple-configuration test runs.  Please see

btw., you can unset CONFIG_ALLOW_WARNINGS in -tip kernels to turn 
build warnings into build failures - and those are harder to miss.
