Results from Linaro’s test farm.
No regressions on arm64, arm, x86_64, and i386.
Tested-by: Linux Kernel Functional Testing <lkft@...aro.org>
NOTE:
Following two issues are not specific to this round of review,
We have been noticing on stable-rc 6.4.1-rc1 release with
kselftest merge configs builds testing selftests: net tests.
1)
While running selftests: net: pmtu.sh on arm64 ARM juno-r2, qemu-arm64
and Raspberry Pi 4 Model B following kernel crash reported.
