Last year when I ran 'matrixprod', I could boost the code coverage in tree.c by ~5% (80 to 85%). I am planning to run more RCU-strenous loads like stress-ng's 'dirmany' stressor and collect coverage. Also perhaps we can span more than one stressor in a default stress-ng invocation to add some variety and concurrency to the workloads. Joel Fernandes (Google) (5): rcutorture: kvm: Simplify invocation of mkinitrd.sh rcutorture: Add a stress-ng build script rcutorture: mkinitrd: Allow to run optional commands passed to it rcutorture: mkinitrd: Use previous init.c to check if rebuild needed rcutorture: kvm: Invoke stress-ng building it if necessary tools/testing/selftests/rcutorture/bin/kvm.sh | 39 +++++++-- .../selftests/rcutorture/bin/mkinitrd.sh | 59 +++++++++++-- .../selftests/rcutorture/bin/mkstress-ng.sh | 86 +++++++++++++++++++ 3 files changed, 171 insertions(+), 13 deletions(-) create mode 100755 tools/testing/selftests/rcutorture/bin/mkstress-ng.sh -- 2.34.1
