Greeting,

FYI, we noticed the following commit (built with gcc-11):

commit: b3830bad81e872632431363853c810c5f652a040 ("[PATCH v3 2/8] kbuild: rebuild .vmlinux.export.o when its prerequisite is updated")

I think this is a false-positive alarm.

As I replied before [1], I know my patch set is broken.
I think 0day bot is testing the patch set I had already retracted.

I only picked up low-hanging fruits with fixes to my tree,
and did boot tests.

Please let me know if linux-next is broken.

Sorry for this false-positive report.

Thanks for the info, we noticed that this patch has been merged into
linux-next, so we tested below commits:

b9f85101cad33 (tag: next-20221011, linux-next/master) Add linux-next specific files for 20221011
5d4aeffbf7092 kbuild: rebuild .vmlinux.export.o when its prerequisite is updated

They all passed the boot tests.
