Hello,

We ran automated tests on a recent commit from this kernel tree:

Kernel repo: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git Commit: b76700d518a4 - mptcp: free acked data before waiting for more memory

The results of these automated tests are provided below.

Overall result: PASSED Merge: OK Compile: OK Tests: OK

All kernel binaries, config files, and logs are available for download here:

Please reply to this email if you have any questions about the tests that we ran or if you have any suggestions on how to make future tests more effective.

Compile testing ---------------

We compiled the kernel for 4 architectures:

aarch64: make options: make -j30 INSTALL_MOD_STRIP=1 targz-pkg

ppc64le: make options: make -j30 INSTALL_MOD_STRIP=1 targz-pkg

s390x: make options: make -j30 INSTALL_MOD_STRIP=1 targz-pkg

x86_64: make options: make -j30 INSTALL_MOD_STRIP=1 targz-pkg

Hardware testing ---------------- We booted each kernel and ran the following tests:

⚡ Internal infrastructure issues prevented one or more tests (marked with ⚡⚡⚡) from running on this architecture. This is not the fault of the kernel that was tested.

Aborted tests ------------- Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report.

Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed.

Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱.
