29494845cd ("mm: prepare to premature release of .."): BUG: sleeping function called from invalid context at fs/dcache.c:843

by kernel test robot

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://github.com/rgushchin/linux.git release_percpu commit 29494845cd7475005dceb653a4b458febd5f81ce Author: Roman Gushchin <guro(a)fb.com> AuthorDate: Fri Mar 1 12:53:25 2019 -0800 Commit: Roman Gushchin <guro(a)fb.com> CommitDate: Mon Mar 4 10:52:15 2019 -0800 mm: prepare to premature release of memcg->vmstats_percpu Prepare to handle premature release of memcg->vmstats_percpu data. Currently it's a generic pointer which is expected to be non-NULL during the whole life time of a memcg. Switch over to the rcu-protected pointer, and carefully check it for being non-NULL. This change is a required step towards dynamic premature release of percpu memcg data.

2d32f12eef: vm-scalability.median -3.5% regression

by kernel test robot

Greeting, FYI, we noticed a -3.5% regression of vm-scalability.median due to commit: commit: 2d32f12eefe7965cfab08a68fd793e7d96522462 ("[-mm only] mm/shuffle: Default enable all shuffling") git://internal_merge_and_test_tree devel-catchup-201902220840 in testcase: vm-scalability on test machine: 104 threads Skylake with 192G memory with following parameters: runtime: 300s size: 8T test:

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 caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace): KERNEL SELFTESTS: linux_headers_dir is /usr/src/linux-headers-x86_64-rhel-7.2-997dd96471641e147cb2c33ad54284000d0f5e35 2019-03-02 12:11:59 ln -sf /usr/bin/clang-7 /usr/bin/clang 2019-03-02 12:11:59 ln -sf /usr/bin/llc-7 /usr/bin/llc media_tests test: not in Makefile 2019-03-02 12:11:59 make TARGETS=media_tests make[1]: Entering directory '/usr/src/perf_selftests-x86_64-rhel-7.2-997dd96471641e147cb2c33ad54284000d0f5e35/tools/testing/selftests/media_tests' gcc -I../ -I../../../../usr/include/ media_device_test.c -o /usr/src/perf_selftests-x86_64-rhel-7.2-997dd96471641e147cb2c33ad54284000d0f5e35/tools/testing/selftests/media_tests/media_device_test gcc -I../ -I../../../../usr/include/ media_device_open.c -o /usr/src/perf_selftests-x86_64-rhel-7.2-997dd96471641e147cb2c33ad54284000d0f5e35/tools/testing/selftests/media_tests/media_device_open gcc -I../ -I../../../../usr/include/ video_device_test.c -o /usr/src/perf_selftests-x86_64-rhel-7.2-997dd96471641e147cb2c33ad54284000d0f5e35/tools/testing/selftests/media_tests/video_device_test make[1]: Leaving directory '/usr/src/perf_selftests-x86_64-rhel-7.2-997dd96471641e147cb2c33ad54284000d0f5e35/tools/testing/selftests/media_tests' ignored_by_lkp media_tests test 2019-03-02 12:11:59 make run_tests -C membarrier make: Entering directory '/usr/src/perf_selftests-x86_64-rhel-7.2-997dd96471641e147cb2c33ad54284000d0f5e35/tools/testing/selftests/membarrier' gcc -g -I../../../../usr/include/ membarrier_test.c -o /usr/src/perf_selftests-x86_64-rhel-7.2-997dd96471641e147cb2c33ad54284000d0f5e35/tools/testing/selftests/membarrier/membarrier_test TAP version 13 selftests: membarrier: membarrier_test ======================================== ok 1 sys_membarrier available ok 2 sys membarrier invalid command test: command = -1, flags = 0, errno = 22.
