Subject: Prototype patch to avoid TREE07 rcu_torture_writer() stalls

Hello, Frederic,

You mentioned rcu_torture_writer() stall issues on TREE07. Does the
patch shown below help?

If so, I predict that your bisection will converge on commit af19a2526cba9
("rcutorture: Add mid-sized stall to TREE07").

Thanx, Paul

------------------------------------------------------------------------

commit 7e9794bb7017593da427f555e4e23da2d42744e5
Author: Paul E. McKenney <[email protected]>
Date: Wed Jan 3 10:59:25 2024 -0800

rcutorture: Suppress rtort_pipe_count warnings until after stalls

Currently, if rcu_torture_writer() sees fewer than ten grace periods
having elapsed during a call to stutter_wait() that actually waited,
the rtort_pipe_count warning is emitted. This has worked well for
a long time. Except that the rcutorture TREE07 scenario now does a
short-term 14-second RCU CPU stall, which can most definitely case
false-positive rtort_pipe_count warnings.

This commit therefore changes rcu_torture_writer() to compute the
full expected holdoff and stall duration, and to refuse to report any
rtort_pipe_count warnings until after all stalls have completed.

Hmm, I fear that doesn't help.

Nope I can reproduce several releases back (at least since 6.4 but maybe
even before).

Ten seconds to get from the start of the stall to printing out the
"starved" message? That is unusual. Unless you have slow console
or something.

Maybe things are stacked up behind a CPU spinning with interrupts
disabled? That would cause trouble for smp_call_function_single().

This looks like the same cause, CPU 11.

Before checking the guest's dmesg, I should probably have checked the host's.
It seems to report some softlockups, perhaps due to too many instances
in parallel where memory is not that generous.

Let me try to run as much time (250 hours) but with fewer instances in
parallel.

That would do it!

I just today saw an extended stall on one instance of TREE03, also
RCU grace-period kthread starvation. But this was in -next, which
is also having other yet-as-unanalyzed issues.

Thanx, Paul
