During the integration of PREEMPT_RT support, the code flow around
memcg_check_events() resulted in `twisted code'. Moving the code around
and avoiding then would then lead to an additional local-irq-save
section within memcg_check_events(). While looking better, it adds a
local-irq-save section to code flow which is usually within an
local-irq-off block on non-PREEMPT_RT configurations.
The threshold event handler is a deprecated memcg v1 feature. Instead of
trying to get it to work under PREEMPT_RT just disable it. There should
be no users on PREEMPT_RT. From that perspective it makes even less
sense to get it to work under PREEMPT_RT while having zero users.
Make memory.soft_limit_in_bytes and cgroup.event_control return
-EOPNOTSUPP on PREEMPT_RT. Make an empty memcg_check_events() and
memcg_write_event_control() which return only -EOPNOTSUPP on PREEMPT_RT.
Document that the two knobs are disabled on PREEMPT_RT. Shuffle the code around
so that all unused function are in on #ifdef block.

I still support this approach but the patch is much larger than
necessary. The code moving shouldn't be really necessary and a simple
"do not allow" to set any thresholds or soft limit should be good
enough.
While in general it is better to disable the unreachable code I do not
think this is worth the code churn here.

I got the "defined but not used" warnings by the compiler after I
disabled the two functions. Then I moved everything to one code block to
avoid the multiple ifdefs.
If that is not good, let me think of something else…

That would be one way but it is not obvious that the eventfd/ signal
part of the code is not invoked. And why keep dead code around?

If this is really needed then just split the patch into two. First to
add the special RT handling and the other one to move the code without
any other changes.

The per-CPU counter are modified with the non-atomic modifier. The
consistency is ensured by disabling interrupts for the update.
On non PREEMPT_RT configuration this works because acquiring a
spinlock_t typed lock with the _irq() suffix disables interrupts. On
PREEMPT_RT configurations the RMW operation can be interrupted.
Another problem is that mem_cgroup_swapout() expects to be invoked with
disabled interrupts because the caller has to acquire a spinlock_t which
is acquired with disabled interrupts. Since spinlock_t never disables
interrupts on PREEMPT_RT the interrupts are never disabled at this
point.
The code is never called from in_irq() context on PREEMPT_RT therefore
disabling preemption during the update is sufficient on PREEMPT_RT.
The sections which explicitly disable interrupts can remain on
PREEMPT_RT because the sections remain short and they don't involve
sleeping locks (memcg_check_events() is doing nothing on PREEMPT_RT).
Disable preemption during update of the per-CPU variables which do not
explicitly disable interrupts.

So it's like c68ed7945701 ("mm/vmstat: protect per cpu variables with
preempt disable on RT") but we still don't want a wrapper of those
constructs so they don't spread further, right :)

Right. We only have them because of assumption based on spin_lock_irq()
which are not true on PREEMPT_RT. Having a generic one might let people
to use them for the wrong reasons.
The commit you mentioned changed all users while here I only changed
those which missed it. Also I wasn't sure if preemption should be
disabled or interrupts (to align with the other local_irq_save()).

I can see that you have already discussed the choice for open coded
version with Vlastimil. I do not have a strong opinion but I have to say
I dislike the construct because it is not really clear just from reading
the code. A wrapper could go and explain the underlying problem -
including potential asserts for !PREEMPT_RT. One way or the other the
change looks correct AFAICS.

The members of the per-CPU structure memcg_stock_pcp are protected
either by disabling interrupts or by disabling preemption if the
invocation occurred in process context.
Disabling interrupts protects most of the structure excluding task_obj
while disabling preemption protects only task_obj.
This schema is incompatible with PREEMPT_RT because it creates atomic
context in which actions are performed which require preemptible
context. One example is obj_cgroup_release().
The IRQ-disable and preempt-disable sections can be replaced with
local_lock_t which preserves the explicit disabling of interrupts while
keeps the code preemptible on PREEMPT_RT.
The task_obj has been added for performance reason on non-preemptible
kernels where preempt_disable() is a NOP. On the PREEMPT_RT preemption
model preempt_disable() is always implemented. Also there are no memory
allocations in_irq() context and softirqs are processed in (preemptible)
process context. Therefore it makes sense to avoid using task_obj.
Don't use task_obj on PREEMPT_RT and replace manual disabling of
interrupts with a local_lock_t. This change requires some factoring:
- drain_obj_stock() drops a reference on obj_cgroup which leads to an
invocation of obj_cgroup_release() if it is the last object. This in
turn leads to recursive locking of the local_lock_t. To avoid this,
obj_cgroup_release() is invoked outside of the locked section.
- drain_obj_stock() gets a memcg_stock_pcp passed if the stock_lock has been
acquired (instead of the task_obj_lock) to avoid recursive locking later
in refill_stock().
- drain_all_stock() disables preemption via get_cpu() and then invokes
drain_local_stock() if it is the local CPU to avoid scheduling a worker
(which invokes the same function). Disabling preemption here is
problematic due to the sleeping locks in drain_local_stock().
This can be avoided by always scheduling a worker, even for the local
CPU. Using cpus_read_lock() stabilizes cpu_online_mask which ensures
that no worker is scheduled for an offline CPU. Since there is no
flush_work(), it is still possible that a worker is invoked on the wrong
CPU but it is okay since it operates always on the local-CPU data.
- drain_local_stock() is always invoked as a worker so it can be optimized
by removing in_task() (it is always true) and avoiding the "irq_save"
variant because interrupts are always enabled here. Operating on
task_obj first allows to acquire the lock_lock_t without lockdep
complains.

I do not see any obvious problem with this patch. The code is ugly as
hell, though, but a large part of that is because of the weird locking
scheme we already have. I've had a look at 559271146efc ("mm/memcg:
optimize user context object stock access") and while I agree that it
makes sense to optimize for user context I do not really see any numbers
justifying the awkward locking scheme. Is this complexity really worth
it?

OPT is code as-is while "NO-OPT" is with the following patch which
disables the optimisation (so it should be a revert of the optimisation
commit).
ALLOC/FREE is kfree(kmalloc()).
ALLOC/FREE BH is the same but in_interrupt() reported true.
The numbers are are time needed in ns for 100,000,000 iterations of the
free+alloc. SD is standard deviation.
I also let the test run on a Zen2 box:

Thanks! This gives us some picture from the microbenchmark POV. I was
more interested in some real life representative benchmarks. In other
words does the optimization from Weiman make any visible difference for
any real life workload?
Sorry, I know that this all is not really related to your work but if
the original optimization is solely based on artificial benchmarks then
I would rather drop it and also make your RT patchset easier.

my understanding is that this was micro-benchmark driven.

Do you have any real-world benchmark in mind? Like something that is
already used for testing/ benchmarking and would fit here?

Weiman was this driven by any real world workload?

Anything that even remotely resembles a real allocation heavy workload.

So I figured out that build the kernel as user triggers the allocation
path in_task() and in_interrupt(). I booted a PREEMPT_NONE kernel and
run "perf stat -r 5 b.sh" where b.sh unpacks a kernel and runs a
allmodconfig build on /dev/shm. The slow disk should not be a problem.

Thanks for this test. I do assume that both have been run inside a
non-root memcg.
Weiman, what was the original motivation for 559271146efc0? Because as
this RT patch shows it makes future changes much more complex and I
would prefer a simpler and easier to maintain code than some micro
optimizations that do not have any visible effect on real workloads.

I did run after a regular login on a Debian unstable installation. I did
confirm via trace_printk() that get_obj_stock() was invoked from process
and interrupt context and the caller was cc1 and so on.

commit 559271146efc0 is a part of patch series "mm/memcg: Reduce
kmemcache memory accounting overhead". For perf numbers you can see
the cover letter in the commit fdbcb2a6d677 ("mm/memcg: move
mod_objcg_state() to memcontrol.c").
BTW I am onboard with preferring simpler code over complicated optimized code.

Thanks for the pointer! This helped because I couldn't follow the
original series[1].
I definitely do not want to dispute the whole series. It is this
particular patch which makes further changes much more complex AFAICS
and the cost/benefit should be re-evaluated IMHO. Microbenchmarks are a
nice indecation but in this case we should be more re-evaluate. The
complexity has increased even more for RT requirements.
[1] It would be great if those patch specific benchmarks were in the
specific patch next time. This would make it much more easier to track.
Just as an exercise I have tried to revert 559271146efc0. It needs some
tweaking (on top of Linus tree) and I hope I got everything right.
Sebastian does this help for the RT case?

Looks like this was maybe true in some previous version but now
drain_obj_stock() gets a bool parameter that is passed to
obj_cgroup_uncharge_pages(). But drain_local_stock() uses a NULL or
stock_pcp for that bool parameter which is weird.

The problem is that this pattern where get_obj_stock() sets a
stock_lock_acquried bool and this is passed down and acted upon elsewhere,
is a well known massive red flag for Linus :/
Maybe we should indeed just revert 559271146efc, as Michal noted there were
no hard numbers to justify it, and in previous discussion it seemed to
surface that the costs of irq disable/enable are not that bad on recent cpus
as assumed?

buh. Sorry, that is a left over and should have been true/false instead.

I added some number, fell free re-run.
Let me know if a revert is preferred or you want to keep that so that I

An acceptable form of this would have to basically replace the bool
stock_lock_acquried with two variants of the code paths that rely on it,
feel free to read though the previous occurence :)

I did that locally already. I was referring to the revert.
So repost with bool fixed and the revert will be discussed later or
include the revert at the begin of the series and then rebase these
patches on top of it? I probably don't get to it before FRI so I don't
try to rush anyone here ;)

If you start with the revert then you should be able to get rid of a lot
of complexity, right? We still haven't heard from Weiman about his
original optimization reasoning. There might be good reasons for it
which just hasn't been explicitly mentioned yet.
As already said, if the optimization is visible only in microbenchmarks
without any real workload benefiting from it I would rather consider
reverting it and make the RT addoption easier. Micro optimizations can
always be done on top.

Based on my understanding the optimisation with task_obj for in_task()
mask sense on non-PREEMPTIBLE kernels because preempt_disable()/enable()
is optimized away. This could be then restricted to !CONFIG_PREEMPTION kernel
instead to only PREEMPT_RT.
With CONFIG_PREEMPT_DYNAMIC a non-PREEMPTIBLE kernel can also be
configured but these kernels always have preempt_disable()/enable()
present so it probably makes no sense here for the optimisation.
I did a micro benchmark with disabled interrupts and a loop of
100.000.000 invokcations of kfree(kmalloc()). Based on the results it
makes no sense to add an exception based on dynamic preemption.
Restrict the optimisation to !CONFIG_PREEMPTION kernels.

This isn't a terribly useful [0/n], sorry. It would be better to have
something self-contained which doesn't require that the reader chase
down increasingly old links and figure out what changed during
successive iterations.

Is this a new issue?
Does this happen with these patches when CONFIG_PREEMPT_RT=n?

Similarly, is this caused by these patches? Is it only triggered under
preempt_rt?

Ditto.

I'm sorry. I didn't want to copy the numbers and make the impression of
doing the numbers now on -rc1.

No, I saw it already on 5.16.0-rc5.

Yes. The problem reported by the test is independent of the series and
RT.

Also happens regardless of these patches and RT. It does not happen
always so sometimes I had to run test_core and test_freezer a few times
until lockdep complained.
