Subject: [GIT pull] core/debugobjects for v6.5-rc1

Linus,

please pull the latest core/debugobjects branch from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git core-debugobjects-2023-06-26

up to: 8b64d420fe24: debugobjects: Recheck debug_objects_enabled before reporting


A single update for debug objects:

- Recheck whether debug objects is enabled before reporting a problem to
avoid spamming the logs with messages which are caused by a concurrent
OOM.

Thanks,

tglx
