No regressions on arm64, arm, x86_64, and i386.
I got proc-uptime-001: proc-uptime-001.c:39: main: Assertion `i1 >= i0' failed.
It is a known intermittent failure due to test running more than expected time and runner script killed it.
I have noticed intermittent failures on slow devices.
You can see the history of the test case on Linux next here intermittently failing. I do compare between the stable-rc branches, Linux mainline and next. https://qa-reports.linaro.org/lkft/linux-next-master/build/next-20210924/tes...
I don't see proc-uptime-001 on https://github.com/Linaro/test-definitions/blob/master/automated/linux/kself...
We will add this as known intermittent failure. It would be great if we report this to the test author and ask them to review the test case for the reason for long run time on slow devices.
my proc-uptime-001 history
In general when a test fails, Please re-run the test independently for 10 times or more on the same kernel / device before we report it as regression.
5.10.80-rc2-dirty:not ok 10 selftests: proc: proc-uptime-001 # exit=134
exit=134 which means Aborted. When the test runs more than X time (45 sec i guess) the script will be killed by the runner script.
5.10.80-rc1-dirty:ok 10 selftests: proc: proc-uptime-001
This test log details gives more insight that the test was timeout and Aborted.

However, It is good to find that system running slowly.
