Subject: Re: [PATCH 10/10] kunit: slub: add module description

Hello,


I am observing this warning on the mainline kernel on IBM Power9 Server. Similar warnings are reported on the linux-next as well [1] .

WARNING: modpost: missing MODULE_DESCRIPTION() in lib/tests/slub_kunit.o

Repo: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

HEAD Commit: 0af2f6be1b4281385b618cb86ad946eded089ac8.

[1]: https://lore.kernel.org/all/20250407084858.74a128d2@canb.auug.org.au/

I have made below changes and it fixes the issue.

diff --git a/lib/tests/slub_kunit.c b/lib/tests/slub_kunit.c

If its acceptable please add below tag.
