Results from Linaro’s test farm. No regressions on arm64, arm, x86_64, and i386.
Tested-by: Linux Kernel Functional Testing lkft@linaro.org
NOTE: LTP version upgrade to LTP 20210927. The new case "cfs_bandwidth01" found the following warning. Since it is a new test case that found this warning can not be considered as regression. This warning is only seen on stable rc 4.19 but not found on 4.14, 5.4, 5.10 and 5.14.
Test output log:

FWIW this appears to be the bug the test is intended to reproduce. Originally seen on a SUSE enterprise 4.12 kernel.
