Subject: [mm] 6471384af2:
phoronix-test-suite.darktable.Masskrug.CPU-only.seconds 10.2% regression
Greeting,
FYI, we noticed a 10.2% regression of phoronix-test-suite.darktable.Masskrug.CPU-only.seconds due to commit:
commit: 6471384af2a6530696fc0203bafe4de41a23c9ef ("mm: security: introduce init_on_alloc=1 and init_on_free=1 boot options")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: phoronix-test-suite
on test machine: 12 threads Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz with 8G memory
with following parameters:
test: darktable-1.0.4
cpufreq_governor: performance
test-description: The Phoronix Test Suite is the most comprehensive testing and benchmarking platform available that provides an extensible framework for which new tests can be easily added.
test-url: http://www.phoronix-test-suite.com/
In addition to that, the commit also has significant impact on the following tests:
