Clear buddies on yield, so that the buddy rules don't schedule them despite them being placed right-most.

This fixed a performance regression with yield-happy binary JVMs.

had a quick look again: i believe this one still triggers, and it's caused by some interaction between input code and workqueue code. I think it started triggering when Oleg's workqueue annotation patches went upstream:

6af8bf3: workqueues: add comments to __create_workqueue_key() 8448502: workqueues: do CPU_UP_CANCELED if CPU_UP_PREPARE fails 8de6d30: workqueues: schedule_on_each_cpu() can use schedule_work_on()
ef1ca23: workqueues: queue_work() can use queue_work_on()
a67da70: workqueues: lockdep annotations for flush_work() 3da1c84: workqueues: make get_online_cpus() useable for work->func() 8616a89: workqueues: schedule_on_each_cpu: use flush_work()
db70089: workqueues: implement flush_work()
1a4d9b0: workqueues: insert_work: use "list_head *" instead of "int tail"

plus when the cpu_active_map changes went upstream:

e761b77: cpu hotplug, sched: Introduce cpu_active_map and redo sched domain ma

so it's possibly an old input layer locking problem that only got exposed via current changes. It's not an input layer bug that got introduced ~80 days ago, but possibly an input layer problem. Or a CPU hotplug bug. Or a workqueue bug.

Ingo

"make get_online_cpus() useable for work->func()" changed the locking. destroy_workqueue() was changed to take cpu_maps_update_begin() instead of get_online_cpus(). Other patches can't make any difference afaics.

Currently I don't understand why lockdep complains, will try to do more grepping later.

Oleg.

I check original report.
Is this really cpu hotplug related warnings?

it seem simple ABBA lock, right?

input_dev->mutex != device->sem

What is the kernel version, btw? I can't find do_async_initcalls in 2.6.27 or 2.6.28.

Anyway, this really looks like lockdep bug to me. Even if we really have the circular dependency (will try to grep more) I can't understand why lockdep claims that polldev_mutex depends on cpu_add_remove_lock.

Oleg.

i suspect it's an older version of tip/master that still had async initcalls.

ok, will re-report if i can trigger it again with latest kernels. Rafael, please close this bug as cannot-reproduce for now.

Ingo

Done.

Thanks,
Rafael

The cause has been found - a bug in the dpt_i2o driver that was hidden until 2.6.27.

I've submitted a patch for 2.6.28 which will be included in the next -rc, at which point I will submit it for 2.6.27-stable as well.

Thanks

Mike.

Thanks for the info.

Can you please put a pointer to the patch into the Bugzilla entry?

Rafael

Actually, that's not quite the way it works anymore. As long as the
patch is similar for both trees, the way it's done now is to tag stable
patches with cc: Stable Tree <[email protected]> so they have automatic notifies to the stable tree.

I'm assuming this patch should be so tagged?

James

Oh OK, I did not know that. The patch applies indeed to .27 and .28 .

Yes, thank you.

Mike.

This has been fixed already in .27 and in mainline with a patch from Alan.

thanks,

OK, closed it.

Do you remember which of the Alan's patches is that?

It wasn't a patch from Alan. It was from me. The commit ID is c82732a42896364296599b0f73f01c5e3fd781ae

OK, thanks.

I added the "Fixed by" information to the bug entry, for the record.

I wasn't one of mine. The patch was written by Mike Isely: commit c82732a42896364296599b0f73f01c5e3fd781ae.
