Letting it run long enough, I was able to trigger it.
I think I know what's wrong with it. I'll put in some debugging to see if
my thoughts are accurate.
Thanks for bringing this back to my attention.

[software node] 7589238a8c: BUG:kernel_NULL_pointer_dereference,address
by kernel test robot
Greeting,
FYI, we noticed the following commit (built with gcc-7):
commit: 7589238a8cf37331607c3222a64ac3140b29532d ("Revert "software node: Simplify software_node_release() function"")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: kernel-selftests
with following parameters:
group: kselftests-lib
test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt
on test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 8G
caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):
If you fix the issue, kindly add following tag

Can you send me the config for where you can reproduce it on x86?
The iterator now doesn't stop the ring buffer when it iterates, and is
doing so over a live buffer (but should be able to handle it). It's
triggering something I thought wasn't suppose to happen (which must be
happening).
Perhaps with your config I'd be able to reproduce it.

[firmware] 88a5883981: will-it-scale.per_thread_ops -66.8% regression
by kernel test robot
Greeting,
FYI, we noticed a -66.8% regression of will-it-scale.per_thread_ops due to commit:
commit: 88a588398167c06f3890949fe60e864fa75a6f21 ("[PATCH 1/1] firmware: arm_scmi/mailbox: ignore notification for tx done using irq")
url: https://github.com/0day-ci/linux/commits/joe_zhuchg-126-com/firmware-arm_...
in testcase: will-it-scale
on test machine: 104 threads Skylake with 192G memory
with following parameters:
nr_task: 100%
mode: thread
test: sched_yield
cpufreq_governor: performance
ucode: 0x2000065
test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <rong.a.chen(a)intel.com>
