preempt_disable() is a no-op when !CONFIG_PREEMPT_COUNT, right?

[btrfs] 302167c50b: fio.write_bw_MBps -12.4% regression
by kernel test robot
Greeting,
FYI, we noticed a -12.4% regression of fio.write_bw_MBps due to commit:
commit: 302167c50b32e7fccc98994a91d40ddbbab04e52 ("btrfs: don't end the transaction for delayed refs in throttle")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git pending-fixes
in testcase: fio-basic
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 64G memory
with following parameters:
runtime: 300s
nr_task: 8t
disk: 1SSD
fs: btrfs
rw: randwrite
bs: 4k
ioengine: sync
test_size: 400g
cpufreq_governor: performance
ucode: 0xb00002e
test-description: Fio is a tool that will spawn a number of threads or processes doing a particular type of I/O action as specified by the user.
test-url: https://github.com/axboe/fio
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests

[mm] ac5b2c1891: vm-scalability.throughput -61.3% regression
by kernel test robot
Greeting,
FYI, we noticed a -61.3% regression of vm-scalability.throughput due to commit:
commit: ac5b2c18911ffe95c08d69273917f90212cf5659 ("mm: thp: relax __GFP_THISNODE for MADV_HUGEPAGE mappings")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: vm-scalability
on test machine: 72 threads Intel(R) Xeon(R) CPU E5-2699 v3 @ 2.30GHz with 128G memory
with following parameters:
runtime: 300
thp_enabled: always
thp_defrag: always
nr_task: 32
nr_ssd: 1
test: swap-w-seq
ucode: 0x3d
cpufreq_governor: performance
test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/
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

[proc] 3f02daf340: kernel_selftests.proc.proc-pid-vm.fail
by kernel test robot
FYI, we noticed the following commit (built with gcc-7):
commit: 3f02daf3406e77d938c20ebd37c2ca74e3779a85 ("[PATCH] proc: test /proc/*/maps, smaps, smaps_rollup, statm")
url: https://github.com/0day-ci/linux/commits/Alexey-Dobriyan/proc-test-proc-m...
base: https://git.kernel.org/cgit/linux/kernel/git/shuah/linux-kselftest.git next
in testcase: kernel_selftests
with following parameters:
group: kselftests-02
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

Test series 1, behavior when no attr struct passed to mq_open:
Kernel supports setting defaults separately from maximums: PASS
Given sane values, mq_open without an attr struct succeeds: PASS
Kernel properly honors default setting knobs: PASS
Kernel properly limits default values to lesser of default/max: PASS
Kernel properly fails to create queue when defaults would
exceed rlimit: PASS
Test series 2, behavior when attr struct is passed to mq_open:
Queue open in excess of rlimit max when euid = 0 failed: PASS
Queue open with mq_maxmsg > limit when euid = 0 succeeded: PASS
Queue open with mq_msgsize > limit when euid = 0 succeeded: PASS
Queue open with total size > 2GB when euid = 0 failed: PASS
Queue open in excess of rlimit max when euid = 99 failed: PASS
Queue open with mq_maxmsg > limit when euid = 99 failed: PASS
Queue open with mq_msgsize > limit when euid = 99 failed: PASS
Queue open with total size > 2GB when euid = 99 failed: PASS

[page cache] eb797a8ee0: vm-scalability.throughput -16.5% regression
by kernel test robot
Greeting,
FYI, we noticed a -16.5% regression of vm-scalability.throughput due to commit:
commit: eb797a8ee0ab4cd03df556980ce7bf167cadaa50 ("page cache: Rearrange address_space")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: vm-scalability
on test machine: 80 threads Skylake with 64G memory
with following parameters:
runtime: 300s
test: small-allocs
cpufreq_governor: performance
test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/
In addition to that, the commit also has significant impact on the following tests:
+------------------+----------------------------------------------------------------------+
| testcase: change | unixbench: unixbench.score 20.9% improvement |
| test machine | 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 64G memory |
| test parameters | cpufreq_governor=performance |
| | nr_task=100% |
| | runtime=300s |
| | test=shell8 |
| | ucode=0xb00002e |
+------------------+----------------------------------------------------------------------+
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

[sched/fair] 2c83362734: pft.faults_per_sec_per_cpu -41.4% regression
by kernel test robot
Greeting,
FYI, we noticed a -41.4% regression of pft.faults_per_sec_per_cpu due to commit:
commit: 2c83362734dad8e48ccc0710b5cd2436a0323893 ("sched/fair: Consider SD_NUMA when selecting the most idle group to schedule on")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: pft
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 64G memory
with following parameters:
runtime: 300s
nr_task: 50%
cpufreq_governor: performance
ucode: 0xb00002e
test-description: Pft is the page fault test micro benchmark.
test-url: https://github.com/gormanm/pft
In addition to that, the commit also has significant impact on the following tests:

[mm/gup] cdaa813278: kernel_selftests.memfd.run_fuse_test.sh.fail
by kernel test robot
FYI, we noticed the following commit (built with gcc-7):
commit: cdaa813278ddc616ee201eacda77f63996b5dd2d ("[PATCH 4/6] mm/gup: track gup-pinned pages")
url: https://github.com/0day-ci/linux/commits/john-hubbard-gmail-com/RFC-v2-mm...
in testcase: kernel_selftests
with following parameters:
group: kselftests-02
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

exceed rlimit: PASS
