I agree that this topic is important (and I believe some other CKI people
made that clear as well) so I added it to the agenda topics. The list of
those is getting long so we'd definitely need to curate it properly soon
but I'll make sure this stays there.
Thanks for the interest!

[tcp] 0b7d7f6b22: netperf.Throughput_Mbps 9.7% improvement
by kernel test robot
Greeting,
FYI, we noticed a 9.7% improvement of netperf.Throughput_Mbps due to commit:
commit: 0b7d7f6b22084a3156f267c85303908a8f4c9a08 ("tcp: add tcp_tx_skb_cache sysctl")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: netperf
on test machine: 40 threads Skylake-SP with 64G memory
with following parameters:
ip: ipv4
runtime: 900s
nr_threads: 25%
cluster: cs-localhost
test: TCP_STREAM
cpufreq_governor: performance
test-description: Netperf is a benchmark that can be use to measure various aspect of networking performance.
test-url: http://www.netperf.org/netperf/
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml

[bpf] 9fe4f05d33: kernel_selftests.bpf.test_verifier.fail
by kernel test robot
FYI, we noticed the following commit (built with gcc-7):
commit: 9fe4f05d33eae0421a065e3bced38905b789c4e8 ("[PATCH v3 bpf-next 4/9] bpf: introduce bounded loops")
url: https://github.com/0day-ci/linux/commits/Alexei-Starovoitov/bpf-bounded-l...
base: https://git.kernel.org/cgit/linux/kernel/git/bpf/bpf-next.git master
in testcase: kernel_selftests
with following parameters:
group: kselftests-00
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 4G
