bb612324ad ("block: warn on un-aligned DMA IO buffer"): WARNING: CPU: 0 PID: 766 at block/blk-merge.c:177 blk_queue_split
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://github.com/0day-ci/linux/commits/Ming-Lei/block-introduce-helpers...
commit bb612324ad90ce8f08869450f132bda22237b369
Author: Ming Lei <ming.lei(a)redhat.com>
AuthorDate: Thu Oct 18 21:18:13 2018 +0800
Commit: 0day robot <lkp(a)intel.com>
CommitDate: Fri Oct 19 10:25:12 2018 +0800
block: warn on un-aligned DMA IO buffer
Now we only check if DMA IO buffer is aligned to queue_dma_alignment()
for pass-through request, and it isn't done for normal IO request.
Given the check has to be done on each bvec, it isn't efficient to add the
check in generic_make_request_checks().
This patch addes one WARN in blk_queue_split() for capturing this issue.

[tcp] a337531b94: netperf.Throughput_Mbps -6.1% regression
by kernel test robot
Greeting,
FYI, we noticed a -6.1% regression of netperf.Throughput_Mbps due to commit:
commit: a337531b942bd8a03e7052444d7e36972aac2d92 ("tcp: up initial rmem to 128KB and SYN rwin to around 64KB")
https://git.kernel.org/cgit/linux/kernel/git/davem/net-next.git master
in testcase: netperf
on test machine: 16 threads Intel(R) Xeon(R) CPU D-1541 @ 2.10GHz with 8G memory
with following parameters:
ip: ipv4
runtime: 900s
nr_threads: 200%
cluster: cs-localhost
test: TCP_STREAM
ucode: 0x7000013
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/
In addition to that, the commit also has significant impact on the following tests:

drm: BUG_ON if passing NULL parent to drm_dev_init
Previous commit removed the only reason why we were allowing NULL as
a parent device. With that resolved, we can enforce nobody else does
that mistake.
With that we can drop the ugly drm_dev_set_unique workaround.
v2: rebase, silence checkpatch "== NULL" warning

on test machine: 8 threads Intel(R) Core(TM) i7 CPU 870 @ 2.93GHz with 6G memory
with following parameters:
runtime: 300s
nr_task: 100%
test: execl
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.

Which to me is more of an indication of beginner-ness.

That seems unlikely as it introduces a compilation warning.
A real intentional backdoor from a nefarious source would
likely be completely correct about compilation and use the
typical commit subject style.
Anyway, who know for certain right now.
I would have suggested David reply with only his second sentence
and maybe a pointer to kernelnewbies or staging.
Just something like:
nack: 'len' has no value before the get_user() call.
Please try to make your first patch in drivers/staging
to get familiar with submitting patches to the kernel.
https://kernelnewbies.org/FirstKernelPatch
Maybe there's utility in creating a filtering and auto-reply
tool for first time patch submitters for all the vger mailing
lists using some combination of previously known submitters
and the 0-day robot to point those first time submitters of
defective patches to kernelnewbies and staging.
cheers, Joe

[bpf] fd978bf7fd: will-it-scale.per_process_ops -4.0% regression
by kernel test robot
Greeting,
FYI, we noticed a -4.0% regression of will-it-scale.per_process_ops due to commit:
commit: fd978bf7fd312581a7ca454a991f0ffb34c4204b ("bpf: Add reference tracking to verifier")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: will-it-scale
on test machine: 80 threads Skylake with 64G memory
with following parameters:
nr_task: 100%
mode: process
test: mmap1
cpufreq_governor: performance
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
In addition to that, the commit also has significant impact on the following tests:
