Hi Randy,

I'm having a heck of a time reproducing this one. Any chance you could
share an exact sha1 for the tree where you're hitting this, and maybe
even the actual .config (just in case the KCONFIG_SEED isn't working
somehow).

I've tried a few linux-next trees as well as the mmotm, mmots and
mainline with the culprit patch applied. No luck reproducing this so far.


Hi Dave,

This is just whatever is in linux-next-20211005, which looks like:

commit 29616f67fcbd (HEAD, tag: next-20211005, origin/master, origin/HEAD)
Author: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Tue Oct 5 19:00:37 2021 +1100

Add linux-next specific files for 20211005
Signed-off-by: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>


I have 2 randconfig files that show this build warning.
One of them is attached.
