Didn't you send an earlier e-mail suggesting no regressions ?

Guenter

It took a while for me to generate a report and find this
selftest: arm64 regressions.

The above said regressions are due to the Qemu version upgrade to 7.2.

With reference to my previous emails,
This is not a kernel regression on stable-rc 6.1, 5.15, and 5.10.

- Naresh

Compiled and booted on my x86_64 and ARM64 test systems. No errors or regressions.

Thanks.
