[sched/fair] 3c29e651e1: hackbench.throughput -15.2% regression

by kernel test robot

Greeting, FYI, we noticed a -15.2% regression of hackbench.throughput due to commit: commit: 3c29e651e16dd3b3179cfb2d055ee9538e37515c ("sched/fair: Fall back to sched-idle CPU if idle CPU isn't found") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: hackbench on test machine: 16 threads Intel(R) Xeon(R) E-2278G CPU @ 3.40GHz with 32G memory with following parameters: nr_threads: 100% mode: threads ipc: pipe cpufreq_governor: performance ucode: 0xca test-description: Hackbench is both a benchmark and a stress test for the Linux kernel scheduler. test-url: https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/sc... In addition to that, the commit also has significant impact on the following tests: +------------------+-----------------------------------------------------------------------+ | testcase: change |

[btrfs] 8d47a0d8f7: fio.write_bw_MBps -28.6% regression

by kernel test robot

Greeting, FYI, we noticed a -28.6% regression of fio.write_bw_MBps due to commit: commit: 8d47a0d8f7947422dd359ac8e462687f81a7a137 ("btrfs: Do mandatory tree block check before submitting bio")

2c7abad740 ("kunit: test: create a single centralized executor .."): [ 409.679449] BUG: kernel NULL pointer dereference, address: 00000000

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/Brendan-Higgins/kunit-create-a-c... commit 2c7abad74010ee4f27b0b1f3c68353171e19967b Author: Alan Maguire <alan.maguire(a)oracle.com> AuthorDate: Thu Jan 30 15:08:08 2020 -0800 Commit: 0day robot <lkp(a)intel.com> CommitDate: Mon Feb 3 03:50:54 2020 +0800 kunit: test: create a single centralized executor for all tests Add a centralized executor to dispatch tests rather than relying on late_initcall to schedule each test suite separately. Centralized execution is for built-in tests only; modules will execute tests when loaded.

[rcu] 76550daa4d: will-it-scale.per_thread_ops -10.5% regression

Greeting, FYI, we noticed a -10.5% regression of will-it-scale.per_thread_ops due to commit: commit: 76550daa4d1edaa8251460bd1d4a11b5df23c1c0 ("rcu: Support kfree_bulk() interface in kfree_rcu()") https://git.kernel.org/cgit/linux/kernel/git/paulmck/linux-rcu.git dev.2020.02.13c in testcase: will-it-scale on test machine: 288 threads Intel(R) Xeon Phi(TM) CPU 7295 @ 1.50GHz with 80G memory with following parameters: nr_task: 100% mode: thread test: open2 cpufreq_governor: performance ucode: 0x11 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
